I think the big problem is Crippling Blow. It has the highest single-target damage output of any non-source ability in the game, and yet it's an AoE and applies a debuff. I really don't think it was meant to dish out that much damage. You talk about Rage being overpowered and stuff, but after you use Rage, what's the first (and often only) ability you use right afterward? It's Crippling Blow. When I was doing one my One Man Army challenge with a knight, I was able to end a fight against 5 enemies in one attack (I did have to use teleport to get the 5th guy close enough, but the other 4 were all together).
That's not to say that Rage isn't overpowered, but I think Larian should only nerf Crippling Blow's damage before looking at reducing the power of anything else warrior-related. I'm pretty sure it's not meant to have such high damage output, anyway.
