How would you fix Warrior?

[PessimiStick]

I have yet to see a single MMO that has actually stuck with a tank that uses differently scaling self-healing as a large portion of their mitigation without admitting they've simply abandoned all efforts at balancing classes. *Every single one* moves away from them because they *always* present overwhelming problems with balance that cannot be addressed. It is an interesting concept, but it is *just not possible* within the realms of a balanced game.

That's not entirely true. See: http://www.wowhead.com/spell=49998

The real key, like you said, is that it has to scale off of *incoming* damage, and not be primarily tied to any stats possessed by the player.
