In light of these quotes, it's pretty much canon that Bane, Revan, and Vitiate are all incredibly powerful, and it's not even remotely arguable. By ignoring this orgy of quotes and continuing to write off these characters as weak because you hate them, you have proven yourself to be immensely biased to the point of complete irrationality.
If you cannot accept this one simple truth, then you have lost all credibility and are confirmed as the sad sack of shit that not only myself, but many other people on here believe you to be.
