He's received decent accolades, like: "People talk about you like you're the next coming of Exar Kun."
He's defeated multiple dark council members (Darth Baras, Darth Vengean, and Darth Ekkage). In the fight with Darth Vengean Draahg is helping you, however at the end of the fight he credits the kill as yours, which leads me to believe the Wrath did most of the work. against Ekkage, she one-shots a sith lord just before fighting you, and in this fight you are helped by some jedi master. Against baras, you fight him by yourself, and Baras is being amped by a sith entity (which some speculate to be Traya) and Sel Makor (an extremely powerful entity, powerful enough to trap the emperor himself). At this point Baras is considered "nigh indestructible."
The Wrath also defeated the Emperor's Voice on Voss while the voice was possessed by Sel Makor. being the Emperor's Wrath he was ahead of every single dark council member except maybe Nox, who is kind of an anomaly.
I think Revan takes this.
This is what I don't like about the game [ToR]. Thanks to Flashpoints, the power of certain invidivuals [such as Wrath 2.0 or Nox] becomes a little harder to analyze. While both have very good feats [Nox arguably having better], the fact that it took them two plus the bounty hunter and the agent of the story to defeat Malgus and Revan is kinda stupid. This only makes their opponents extremely overpowered and leaves you questioning how truly powerful these two individuals [Nox and Wrath] really are.
Problem: Realistically prime Nox/Wrath would solo Malgus. If you really think about it, they (Republic/Empire) don't want to take any chances, so they send a strike team consisting of the best of the best. Plus considering in flashpoints you basically have to fight through an army. It becomes simple to answer when you consider the HoT defeated the Emperor, who is quite a ways above Malgus.

Yeah tbh Revan's skill set isn't good to combat the Wrath. He'd get thrashed in lightsaber combat, and I don't see him utilizing an offensive ability with enough devastating power to overwhelm the Wrath, other than maybe TK, but I don't see that working in this situation. Revan would fare much better against the likes of Nox.
