I think this change is very good. I always used to say that rogues were basically fine and if I were to find a change (besides lolvanish) it would be with kick and taking it off the GCD like a mage and counterspell. I'm very happy to see this change. It was quite annoying having to slow my DPS when expecting a heal soon, and hope I don't trigger a GCD by the time i kick.
For example, fighting a shaman, it's imperative to stop him from healing, but if I use a special attack as he begins casting a heal, by the time I can kick his heal goes off and I kick him without interrupting anything.
Well deserved change imo. Warriors, too, will be happy.
