99% sure talents go into play for this. But I'm not sure on all the specifics. You need what, 50% total haste to reach gcd cap? Raid buffs only provide 8% spell haste, no? (wrath of air + 3% aura) So you need 42% from gear/talents, so a resto druid needs 32% haste? I guess with the lifebloom gcd on it they might have a soft cap for lower, but last I checked lifebloom wasn't a spell druids spammed.
I know disc priests only need 11% haste to gcd cap because of 8% buffs + 6% talents + 25% Borrowed time (after every PW:S) but I don't think druid is anywhere near that low of a requirement.
