For starters, the devs will be doubling player health in the expansion to make characters more durable in PvP. "The net result of these changes is that individual attacks will knock a smaller chunk off of a player's health pool in PvP, but your survivability in PvE won't be affected," Blizzard posted.
Other upcoming changes include reducting base resilience and battle fatigue to practically nil, increasing creature damage, increasing the effectiveness of heals, reducing the power of aborbs, and "making smart heals a little less smart." Some smaller, cheaper healing skills will also be removed from the game, and a few instant-cast heals are on the chopping block as well.
