Ahem. There is no buff coming.

Think of it logically:
  • First of all, what else would the arcane shield improvements be called instead of a buff?
  • Secondly, they have clearly stated that, at the moment, their focus is on PvE not PvP (hence, i.e. no one in QA noticed the imbalacement of Breeze's back-to-back freezes previously) so if you were them, you wouldn't want to make any large adjustments that would further jeopardize the unstable class balance without having a good idea of how PvP works, would you?
  • Third and final point, why bother altering things this late that will probably have to be re-evaluated in a few months with the skill system revamp?


So there you go. Now that this is out of the way, let's all wait patiently for whatever exciting changes the new skill system will bring forth.
