Yes, stripping assault down and focusing on highly talented and buffed attacks only causes it to improve immensely.
My crit rate is 36.57 plus 30% double stacked set bonus.
It is not a significantly hot parse at 70% crit vs the tooltip value of 66,57% on that specific attack.
Difference of less than 5%
But yes, anything affecting the major attack on which everything revolves and which has exceptional critical stats will cause the whole parse to vary significantly.
Wow, that is very high crit. It might cause me to re-think crit rating. I am guessing with base crit that high, that you are also stacking surge even at a slight expense to accuracy? (you missed a few attacks) Be interesting if you would post your stats. I never thought a 36% base crit would be all that great, especially with all the haters right now hating on crit. I know auto-crit classes have a reason to hate it, which is perfectly logical, but maybe I'll have to rethink this a bit.
