That makes so much sense ...oh wait i doesn't haha !
Mastery is good for ....nothing ? its too expansive stats for 1% magic dmg. I rather pick haste cuz casting faster CS makes the spec so much more enjoyable.
Haste is good for slightly more(or not cuz its still fucking rng) procs and so little more focus regen i wonder why i even mentioning it . FD haste values are so fucked up and looks so many players get foolish by it.
Dunno for other specs but at least for surv i know and i test it my self ...dat Rune is a boss and with lil luck can put my burst capabilities on a whole new lvl .I find out that having that 25% crit boost on 22 sec Internal CD is very good and i like it way more then 105icd Mist when it comes to boosting crit chance.
I would say rune is bad for BM and can be really bad for MM but for surv....give me fucking break already !
