@Elmouth:

Warriors already hurt themselves way too much. No other class in the game has built-in cooldowns they are balanced around which cause them to take up to 25% increased damage for a lengthy period of time. I'm talking about Recklessness and Death Wish, of course. Any half-decent warrior will be popping these early, often, and concurrently as much as possible.

Death Wish makes some sense - 5% extra damage taken, 20% increased damage dealt while active - but Recklessness is crazy out of bounds. Three guaranteed yellow crits, but at the cost of 20% additional damage for 12 seconds?! These were OK back in Naxx days where the only things that could kill you were due to your own stupidity, but now where seemingly everything has a pulse AoE component, a skilled DPS warrior is going to take more healing than just about anyone in the raid save the tanks. The only reason this isn't a huge problem is because we have a lot of HP raid- and ICC-buffed. The fact that we end up taking additional damage and thus require closer/more healer attention stands.

Contrast with a class like a shadow priest which can not only keep themselves up while doing competitive DPS but also help heal their party. If you have a heal-sensitive fight, which starts to look like a liability in your raid?
