Nerfing warriors fixes nothing.

Paladin have been and still are horribly designed. Weakest threat modifiers paired with weakest damage= WHAT DID YOU THINK WAS GOING TO HAPPEN!!! Also Sword Oath at level 30 instead of Shield Oath. All the defenses being 20% or a multiple of 20% with bad RNG, an active mitigation that blocks only one of any physical attack. And the poor self sustainability wouldn't be so bad if they didn't tank just as well as everyone else, that is a big NO, NO, when building a "King of Tanks"! Clemency is powered by STR instead of being percentage based, which means it's weak for pure VIT tanks. Let's not forget to mention their only claim to fame: Sentinel and Hallowed Ground, where both of which have very long CDs. And their CDs are too long for them to be relying on them. It's bad so back a lot of PLDs stagger CDs and take the hits unmitigated, making it harder on the healer. Staggering CDs is NOT good tanking! It shows how inefficient and ineffective PLDs really are. DRK are riding the same boat about this. And PLDs are inept at AoE damage, could have had gore blade be an AoE, but NOPE, lets annoyingly flash our glimmer at things and hope we don't get stuck with DPS that is equally as bad at AoE, in which case is usually entirely by cluelessness after level 50.

Oh yes let's not forget how 2.0 made Warriors incapable of tanking, and Paladins the most useless garbage there was because NO THREAT. In fact PLD was patched the most times because of this.
And don't get me started on DRK.

PLD and DRK are bad because of bad design.
