Heard vaguely about it on AJ and tried it myself, i'm sitting at around 20% haste and while it doesn't help our damage that much, focus regen at that point is kind of acceptable. Using Herkuml War Token, reforged most of my gear to haste and 3 Quick Ambers + a Sun Scope (40 haste) on my Weapon.
Anyone else tried it?
We still need fixing, but it seems like a decent band-aid until Blizzard do something about us PvP-Wise.
Edit : Armory is dead, didn't update my toons in days =(.
