It's kinda funny - early in the season they were saying "we don't think burst is a problem in pvp" and now they are effectively saying just the opposite.

Personally, I think they will have to address the healing issue sooner rather than later...some healing classes (resto druids, disc priests) are already very strong in pvp, and this change just makes them stronger.

It will be interesting to see the new arena teams / strats that come from this...

Cheers,
