Alot of eliteists will claim spell speed is useless because of preemptive fights, but for big speed run pulls where you need to throw a large amount of cures out quickly and certain moves like prey on T10 its really handy, with presence of mind and alot of spell speed you could stop both preys on the add phase without even using a swiftcast and give you SCH some time to do some dps (Or carry him xD) Plus Holy spam.

Plus Speed spell is rumored to be getting a buff in 3.0, Where its going to be directly effecting HOT's like Regen and medica 2. WIN.
