So what makes me doubt this is, that im only at 24% haste right now and according to all guides 1st priority is getting 30% haste, if im not mistaken. But using simulationcraft and statweights, the versa neck sims more dps for me.
So if you were me would you go for the haste trinket to get closer to my 30% haste goal -> or trust in SimC and go with whatever sims higher?!?!?!
The Versatility neck sims higher because crit is "shit" therefor simmed lower while versatility is less shit.
The 30% Haste is just the pretty much sweet spot allowed with the shit gear in NH and our shit secondary stats on Tier items.
But as it has been said before, after 4 set and a certain gear level, mastery stats simming higher but still most people try to hover around 25-30% haste cause the spec feels smoother.
