This is some bad news. I know some were expecting the nerf.

... we’re planning on deploying hotfixes that reduce tank damage output across the board ...

So they're dropping tank damage without first raising DPS damage. Going to hurt my team, not just teams of all tanks that many of you are running.

Tanks should still be very very hard to kill in WPvP though.
