So i'd like to try to build Haste + Crit instead of Haste + Mastery today. I see how boomkin's build on haste crit (i know the reason is for the starsurge proc), but with such high crit, its also means more crit on every spell count. And i wonder, with our crit damage is 250% of normal damage today, isn't it make crit considerable to build? i know the proc chance on mastery is pretty high, but its still RnG. Any insight?
