Your point is invalid, because it directly contradicts everything canon in star wars, and the fact that the PT era was "The golden age of the Jedi"
Has anyone at all here substantiated how GL saying vaguely that "Golden Age of the Jedi" equals PT Jedi being the most martially capable of all Jedi in the last 25,000 years? Especially since they haven't had any full-scale total war conflicts in "a thousand years" and their lightsaber training is limited to combating each other to gain in skill; not swatting at Sith and dark Jedi left and right who are trying to kill them?
I'm still curious about that one.
You have at LEAST 5-6 powerhouses in that era, whereas you have 1-2 from different KOTOR/TOTJ eras.
1. Define "powerhouse" and its meaning in this debate. Don't be vague.
2. Where are you getting "1-2 powerhouses" from the KotOR/ToTJ era anyways? Do you even know what you're talking about? Malak, before he became DLotS, was a legendary lightsaber user among his peers and strong in the Force (Strong enough that the Star Forge didn't destroy him as it destroyed the multitude of pretenders who followed him). Kavar, the famed Jedi Guardian, was noted beyond the Outer Rim by the Mandalorians as a "worthy opponent", and he teaches higher end lightsaber forms such as Juyo and Ataru. Kavar's shown knocking out an entire cantina with the Force without even killing anyone in the process.
Bastila was a Force prodigy, able to use Battle Meditation on such a level that her personal security was an issue of the Republic, who sent her under armed escort with at least one of their most capable known soldiers. She was powerful enough even to replace Darth Bandon as Malak's apprentice, and it is Sith tenets that teach only the strong are worthy of attaining power, clearly. Her mere presence at a battle usually determines its outcome.
Ulic Qel-Droma was a master swordsman (and yes, I know you hate it when I use that term) whose skill was absolutely amazing. He stalemated Exar Kun in a pitched battle, and beat down Mandalore while in a precarious position. Even more amazing is that even without the Force, he was able to maintain a defensive duel against an enraged Jedi Sylvar. Ulic's skills with a lightsaber even there outshine your average PT Jedi. I don't see Anoon Bandara or Cin Drallig or Ki-Adi-Mundi doing this.
You have Jedi Masters in these eras with literally awesome powers: some could make matter stronger than a lightsaber (Vodo), others could mindwipe living beings and recreate their memories (KotOR Jedi Council), block Sith from the Force (Nomi, Odan-Urr) and a multitude of other abilities not seen nor exactly surpassed by PT Jedi. Hell, even Luke Skywalker's band of JA misfits show Force control and martial capability surpassing PT Jedi, and it makes sense considering how conflict drove them to become dangerous fighters.
Not to mention, I believe the Clone Wars were even more devastating than the Jedi Civil War(although I prefer to think the Jedi Civil War was the most devastating until the Vong War), so it wasn't all peacetime for the PT Jedi.
Wow, so suddenly we care about what you believe based on what? Gut instinct? Magic 8-ball? The Clone Wars were hardly more "devastating" to the Jedi overall then the Jedi Civil War (though at the end of the former, the Jedi were annihilated, but this is more of a finality; they don't grow from this conflict because they die from it). For one thing, the battle of Geonosis is seen as perhaps the most devastating reversal to Jedi forces during the entire war, and only perhaps 200 Jedi die out of an order of 10,000. During the Jedi Civil War, an order of comparible size was decimated to barely a hundre. Kreia notes that many fell in battle, and even more were seduced to the Dark Side. This battle shattered the Jedi Order because of the conflict, though it drove some to become seasoned warriors. This is a far cry from the Clone Wars, where the majority of the fighting was done by naval ships and Clone Troopers or indigenous forces, with Jedi merely being generals or diplomats as the situation demanded. I mean hell, a year into the Clone Wars, and high-end figures like Kit Fisto and Obi-Wan Kenobi were being sent to be diplomats with a neutral planet who was producing new biodroids. This doesn't strike me as a particularly balls-to-the-wall conflict like the Jedi Civil War where Jedi slew Dark Jedi left and right.
More resources does not equate to more power.
Not precisely; more resources do open one up for more vareity of powers and helps one master those powers. And considering that the Jedi Order itself was founded in a time of conflict and that those teachings trickled down through the ages until the Battle of Ruusan, where Jedi finally put away their battle armor and titles, gave away their troops and navies and became the police force of the Republic which hadn't seen another fullscale war for the next millenia.... Let's be reasonable here- there's nothing to support that PT Jedi are more "militant" or more martially capable than previous era Jedi. Theirs was a time of peace, a time of meditation where one could focus on Niman and not on Makashi, so to speak. It was, yes, a golden age of the Jedi, one where they did not need to fight and slaughter. But peace stagnates. This is universal.
Notice how during the KOTOR time, there was no defense for certain techniques (such as Nihilus' drain), and in the PT era, there are defenses for certain techniques.
Substantiate this, DS. Traya notes that there are "techniques in the Force against which there is no defense", but she does not name these techniques and the FMV shows her being Force pushed into a wall, beaten down physically and then continues with her saying she was broken down, stripped of her powers, and exiled.
And somehow you assert that in the PT era there are "defenses for certain techniques"(Again, being typically vague and showing no valid arguments or sources) and this somehow equates to better PT Jedi in combat? Is this how you think?
While more "lore" was available to ancient jedi/sith, the pt jedi/sith had the chance to capitalize on lost knowledge AND new knowledge.
The Jedi Order as of KotOR had multiple enclaves, libraries, and centers each stockpiled with learning from millenia. Thanks to the machinations of Revan, Malak, and Exar Kun, much was lost or plundered. In the wake of the Jedi Civil War when barely a hundred or so Jedi remained, much was plundered and sold by regular people even (See Dantooine). In case you don't recognize how profound of a loss this is, put it in this light:
The Jedi Order was over 20,000 years old at the time of the Jedi Civil War. Much of this knowledge was lost or misplaced, destroyed, died with the original owners, etc. Four thousand years later, any evidence we have of Jedi lore seems lax and certainly have less incentive to study martial feats. Yes, Jedi are shown to be able to slow their breathing, make sand whirl into an intricate pattern, speed themselves up, etc. But nothing groundbreaking when you compare it. There aren't PT Jedi becoming avatars of the Force through meditation and study. In fact, even for all their efforts, the PT Jedi suffered under a cloak of darkness during the Clone Wars, and they could not even sense a Dark Lord of the Sith in their presence. If this is the best the Jedi have to offer, well... it's pretty substandard.
And again, the point remains that conflict drives a Jedi and builds their abilities. You can even see this in the PT era- compare AotC Anakin and Obi-Wan versus their incarnations three years later- even the limited exposure to war and the Sith has made them absolutely amazing.
Not to mention, having more sith doesn't mean more knowledge. Notice how Sidious, who was 1 of 2 sith at all time during that last millennium, had more sith lore than ANY other sith in the history of star wars.
No, more Sith means more incentive to practice lightsaber duelling styles and tricks, defensive Force feats and so on. The earlier era had more experience in the matter in general, and more reference material. In the PT Jedi era, true lightsaber duelling is considered outdated; it's all about blaster bolt reflection.
And despite your vague, unsubstantied claim about Sidious, the point remains that the era was more warlike and had ready access to martially-focused material. This is evident.
This again, goes against canon. Yoda was the most powerful Jedi up until Luke's time.
Substantiate this. Show a reliable, non-third person source which lists Yoda as "the most powerful Jedi" in Jedi History until Luke Skywalker. Then, put it into context as to how Yoda's station in the Jedi Order reflects on his subordinates as martial Jedi.
Mace's shatterpoint and vaapad abilities made him a saber powerhouse.
But didn't make him better than Yoda, who practiced a lightsaber form thousands of years old. Mace's true strength over his PT Jedi is that he's the most martial-minded of Jedi. He's the one who is fueled by controlled passions and extensive saber practice. However, for all his martial ability and mindset, even Mace Windu is changed by his conflict on Haruun Kal, where he must confront war in person for perhaps the first time during the Clone Wars. He says it himself "Jedi are keepers of the peace; not soldiers". He reinforces their status of Republic policemen, not warriors.
Again, conflict strengthens. It's like the old adage- the blade must pass through the fire, or else it will break when used.
