We've just made two changes to health pools:

* You now get the same +health per level level above 50 as you do up it - previously the gains above 50 were halved. This applies to players and mobs alike, and addresses issues with damage attacks becoming more effective in high-level play.

* Mob health values have been slightly increased across the board.

Both changes are experimental and may see further tweaks depending on how they play out.

On another note, we'll be starting a balancing pass of all the classes soon, so expect some bigger changes there.
