WOW - Upcoming Global Cooldown Fixes : World of Warcraft General Discussions

Recent changes in patch 2.3 changed how the global cooldown behaves. As an unintended result, this has had a cascading effect specifically on players who "spam action bar buttons" to use a particular move right when the cooldown is up.

It is being worked on, both server side changes (some of which have already shipped) as well as client side changes targeted for 2.3.2. The issue is not being ignored.
