Anything that is chance based cannot be tracked. Crit is one of those. The reason why is simply that if you observe a certain number of crits and compare it to ones theoretical crit rate one can only say if one got lucky or unlucky with crits but not what the actual DPS contribution from extra 3% was because one could have been excessively lucky and unlucky.
There is nothing that says: "Oh this crit was now due to the extra crit chance from X".
So unfortunately one cannot faithfully calculate most utility based damage contributions right now.
Ok, but it still stands on the 2% damage increase auras, and such from Paladins, and the hunter BM pet crit effect... That's not chance based at all.
