Kansuke or Renegat. Urgh. Fuck I really don't know. Renegat on his A-game goes 20-0 like it ain't nothing, I've seen him win rounds that I was sure we lost. I find Kansuke harder to fight though in a duel and he mostly uses light armor in battle, which does kinda reduce performance imo. Then there is also Olwen, used to be beast, but wasn't too impressed by his more recent playing.
Going to give my vote to Renegat by a really small margin.
