Been trying to find some info on this and can't seem to locate anything.

I was curious if Skill Speed bonuses only decreased the recast time of your skills, or if it also decreased your global cooldown. Right now it feels like the gcd is about 2 seconds, and I think if there was some way to get it to 1.5 or even 1.7 it would really improve threat generation as well as making interrupts easier.
