wasn't there a haste website that showed how much haste you needed to make certain spells instant?... you could choose the spell and the buffs you would have on, and it would tell you how much haste you would need?... it may have not be updated since cata, but i lost it when i moved over my bookmarks...
trying to figure out as demo how much haste i would need (given my 10 man raid buffs) to push it as close to gcd as possible without sacrificing too much crit or even hit... i just pushed myself over 2k, but now my hit is down to just under 16%...
