Been a while but doesn't Neverwinter online do cooldowns?
Edit* I looked it up they do for encounters and a build up resource for dailies I think. I would say no, I don't agree with this change.
BTW ddo came out roughly around the same time another game came out, guess what it was...World of Warcraft. DDO always had there dedicated fan base, why its still around, but its no WoW.
