Ok so we all know the gcd cap is 50% haste. We'll never reach lb or lvb's haste cap anytime soon, and there's really no number to go for. But one of my main questions is, if I go over the gcd cap (50%) with say lust, berserking or elemental mastery would it be a waste of dps? Like, say I'm stacked to 70% haste I'm over the gcd cap and probably end up doing lower dps in the long run.
I never know exactly when to pop these and go into mastery ever or just go into haste until oblivion.
