I like the combat pace. I wouldn't necessarily mind a 2.0 second base GCD, but I don't feel its necessary.

I hated WoW's 1.5 second CD. I mean, it ended up being more like a 1 second GCD for a lot of specs because Haste was often very good. But it just felt so spammy and trigger happy, particularly on DPS, who were never able to ever stop constantly doing something or their DPS would plummet.

On a side note, though, I do think skillspeed / spellspeed could stand to reduce the cast time / GCD more. Maybe it's different at high level, but I feel like those stats are terrible. I could have speed on every piece of gear and only see like a .1 second drop in cast time.
