Well I tried to run your setup IRL and went outside to test it out on my car. No Chaos Bolt or nothing...=/ then I went inside and reforged abit and then went outside to test again. Nothing again!! Not even a scratch!!
OT though lol, when I was playing Destro for the past 2 weeks, I found running Int>Hit/Exp> Mastery>Crit>>>>Haste to work for me and was getting better results than my Affliction setup.
Are ya weakdots from Arthas?
