I was just messing arouhnd with some talent builds and I started thinking about how much more burst damage mages will have in pvp. From reading the forums it appears that the biggest complaint against mages in pvp is the burst damage they can do. Now, picture hitting target with slow poping macro to do POM, Arcane Power, arcane blast, then arcane blast again (this should be possible since you have "slow" on the target) at this moment, you have 30% more damage from the new arcane blast talent and still have 30% more damage from Arcane Power, the 12% from slow. All that will be proc'd when you then cast arcane barrage. Am I missing something? Do some of these not stack?
