Here's what you and Frobo have posted, in a nutshell.
"Yeah even though he only defeated one person he must be really powerful."
This was ridiculous. To say that Ragnos only killed one person because the only kill we happen to have available to us is named is about as illogical as saying that Han Solo has only killed one Rodian in his lifetime based on what we know from ANH.
"Even though he only ruled over a couple of planets, it's not like any other Sith could possibly rule their entire lives over a couple of planets"
Oh really? So tell me... What other Sith have ruled over a couple of planets populated with Sith? Oh wait... none. Nice try.
"Even though no credible star wars site says anything about these Sith being all powerful or Ragnos being extremely powerful or even mentioning him at all sometimes they must be."
All powerful is never mentioned. Overwhelmingly power? Probably. But if your sole source of information consists of credible Star Wars sites, you shouldn't know who the hell Revan is, because he's not at Starwars.com.
"We know Kreia said that Ragnos posessed tremendous strength, both physically and in the Force"
And that didn't strike you as exceptional that she would even comment on that?
"Kreia the one who never manipulates or lies (telling Handmaiden that the Exile is dead, using the Exile for some ulterior motive to try and destroy the Force, etc.) Kreia said Ragnos had tremendous strength both physically and in the Force so Ragnos must be the most powerful being ever capable of destroying planets by blowing his nose. (Even though Kreia says Revan is power and staring at him was like staring at the heart of the Force back when he was just a Jedi padawan and he would later multiply his power several fold, and Kreia is saying this about someone she actually knew unlike Ragnos)"
What's this all about" You think a historian is going to lie or exaggerate when she's been telling you information that was true and credible since you landed on Korriban? What, you think she just randomnly lied? To what end? If you distrust Kreia so much, what she says about Revan should be equally suspect.
"It's not like Revan was powerful or anything. (Even though Wikipedia, the Free encyclopedia says that Revan is thought by many to be the most powerful Sith Lord of all time) Ragnos or any ancient Sith for that matter would easily fart and destroy Revan and everyone else of his time (1,000 years later)"
Wikipedia is a source anyone can edit, and it's never been an official credible Star Wars site, so why bother quoting it? And since when has everyone thinking Revan is the most powerful ever changed anything? Most people think Sidious and Vader are powerful compard to Revan, and yet they aren't. That changes nothing. But your post here especially is fanboyish to the extreme.
"Revan has the highest level of Battle precog, has the Will power to resist the Dark side of an entire planet that no one else (not even Kreia) could resist, controlled an enormous space station that siphoned the power of a star and killed hundreds of other Sith who tried to control it, is perhaps the greatest tactician ever, has enormously high potential, plunders all the knowledge he could from the Jedi temples, he plundered tombs, relics, artifacts, and knowledge from a planet sized Sith storehouse of knowledge, learned dozens of ways to kill or turn Jedi/Sith, fights for 6 years straight as the leader of one of the main forces in the two different wars against powerful opponents, killing Mandalore and the strongest Echani, and was considered by Kreia (Revan's mentor who could kill three Jedi council members at the same time with one use of the Force) to be the heart of the Force. Then he loses all that power and becomes a Jedi again, he plunders Korriban, including the tombs of four very powerful dark lords, gaining their artifacts, learning from Tulak's holocron, killing two tarentateks at the same time by himself when just one could easily kill a Jedi, he killed everyone in a Sith academy that he started, he killed the best bounty hunter at that time, a Sith Lord, he killed hundreds of dark Jedi and assassin droids, defeated and killed his apprentice Darth Malak at least twice in a row, and became even stronger than he was during his first reign (first paragraph). Then he recovers all his memories and knowledge from Malachor V, the Jedi temples, etc. increasing his power greatly from the second paragraph, before he goes to fight the ancient Sith empire single handedly."
Battle precognition won't save him from being destroyed from a far superior Sith. His will power isn't as big a factor in this battle as you'd imply, and his control over the Star Forge is exceptional but not something totally exclusive. That is, it has yet to be shown just how powerful one must be to control it. Jesus, just reading this reeks of fanboyism... Even I'm getting disgusted with this.
"Now I have never read anywhere that Sadow and Kressh feared him or at least as much as you say."
So just what have you read?
Here's from your friend Frobo...
"he ruled a couple planets which is less then revan did, revan defeated hundreds if not thousands of jedi so a sith magician is no big deal, as for going unchallenged it was manipulation not power."
First off, Frobo has no idea how large the Sith empire was, so he assumes it was a couple of planets. Then he says it is less than what Revan did, even though Revan didn't rule a planet in his life. He was a general, not a ruler. Second, there is no official website or canon source that says Revan even killed five jedi, let alone hundreds or thousands. And nice job of shrugging aside the victory over Simus and the fact that he held his throne for over a century in a Sith land, where the rule is the strongest rule. If Ragnos was NOT the strongest, why did he rule? Answer me that one.
"As for his long rule going "unchallenged" it's pretty easy to go unchallenged when everyone who could put up a fight to you is killing one another instead because you're a lying manipulative SOB. what shows that the fear wasn't justified is that ragnos never fought anyone himself he merely manipulated them into fighting someone else who was stronger. He's no better then sidious he fought once in his life against someone who didn't even have the force and he's hailed as a God around here, why? is it because he outsmarted some sith? is it because someone powerful was afraid of him, many people around the world are afraid of george bush not because of his skill in battle but because of the ressources at his disposal because of what he has at his back. If ragnos could manipulate the sith empire into following him then what would be the point of attacking him if he has the entire empire at his back? he could merely find out about it before hand and have said individual executed as a traitor. The sith probably weren't afraid of ragnos as much as they were of the ressources at his disposal. "
First sentence, nonsense. Second sentence, assumption. Frobo assumes just like you do that Ragnos never fought anybody. Evidence for this? None. Absence of proof is not proof of absence. There were no verified dinosaur bones until the eighteen hundreds. Does that mean there were no dinosaurs that whole time?
"As for the duels, we don't know but going by ragnos's manipulative nature he could have weaseled his way out and we also don't know the caliber of those he fought except for simus so that's pretty much null."
So here Frobo diminishes Ragnos to a weasely manipulator and not a fighter, while giving us NO evidence at all. Not even sound reasoning. Just... boom... opinion and assumption.
"Finally we come to simus. so he was powerful, the power of the force is still greater and it's called force lightning for a reason they may have used magic at the time but the force is ultimatley greater. Even considering that simus was a powerful magician how do we know if he was a great duelist or not what do we know about his saber skills...jack all so we can't really know if he was that good. Revan defeated malak who was drawing on the greatest artifact of a darkside/drawing on a sun for power"
Now, Frobo tries to discredit Simus to totally prove that Ragnos sucks. Frobo assumes that Sith magic is separate from the Force and assumes that the force is greater. Frobo assumes Simus must not be a good duellist because he is a Sith magician, even though every Sith lord -at least- from Exar Kun and before was considered a Sith magician. Frobo then goes on to make the biggest assumption of this post- that the Starforge is the greatest artifact of the darkside, which is ridiculous.
"It's been repeatedly said in this thread and in others, "Ragnos was so powerful that in a time of ancient sith lords no one dared challenge him." Many many many times it's probably been said more then anything else on this forum."
In particular, we know that Naga Sadow and Ludo Kressh even together were afraid of Marka Ragnos. Even when he was dead and had no assets or armies they were afraid of him. why? His power was immense. Or, if you ask Frobo... they must be afraid because he's a weakely manipulative bastard.
