Savage was trained as a warrior all his life and he regained those memories upon Ventress returning them to him in their fight with Dooku. Also Luke never even had a proper lightsaber instructor unlike Savage and he was able to face Vader within a few years. I don't see why you're taking issue with Savage specifically when we have other examples of incredible skill/power growth in the medium. The SWTOR protagonists themselves are great examples of this.
About 90% of the people you mentioned are featless as duelists themselves. Only Scourge and Arcann are any kind of impressive and Arcann only because he beat the HoT who is impressive because he pressed/beat Arcann. Circular logic doesn't work friend. Scourge is only impressive because of his experience but we all know that experience isn't exactly perfect for accurately scaling skill as we can clearly see with Vitiate/Valkorian.
We know they're above them but we don't know how far above them they would be. Then provide the quotes or I won't be able to change my stance.
Why? To both statements.
A quote which only refers to their era.
You didn't respond to the third part of that. If Vitiate was temple busting level on a DS nexus that means he could amp himself to around POD Bane's physical levels but that doesn't mean he'd be as skilled. Are there any skill feats for Vitiate at this point in time aside from having his lightsaber knocked out of his hand by a lightsaber throw?
I'm going to need a video/quote or some form of evidence that the HoT killed Revan cause that's news to me.
We don't know the circumstances of their fight though right?
Fair enough.
Actually you're dead wrong.
Why? Whatever strength disparity between them would be mitigated because of that. It's not like he's hammering away at a Makashi specialist who is specifically weak against strength based fighters.
Wrong yet again.
