Sometimes I really don't understand Blizzard. Back in March, they said they were worried about Paladin burst damage. Fast forward to the WotLK Beta, and we see the following two talents:
Righteous Vengeance (5/5)
Requires 45 Points in Retribution
Increases critical damage bonus of all attacks by 15%.
The Art of War (3/3)
Requires 40 Points in Retribution
Your damaging Crusader Strikes have a 15% chance to cause your next Judgement spell to cause double damage.
Let's say you have a 30% critical strike chance. Your attack possibilities (ignoring misses, parries, etc.) are:
59.5% - Normal damage
10.5% - 2x damage
25.5% - 2.15x damage
4.5% - 4.3x damage
Yes, that's correct. In the current Beta, Retribution paladins have better than Quad Damage!
I think The Art of War is going to be nerfed, and nerfed hard.
