Blizzard finally did some of the necessary nerfing, including making SpellBreakers cost most money/wood/food , requiring an Altar to buy Neutral heros, and making those damn Phoenix things die faster.

Mostly this is the way it played out:

Stop exploit by forcing people to have an altar to buy Neutral heros.

Nerf the humans by making SpellBreakers more costly, and fix the Polymorph exploit.

Buff up the undead a bit because they are still under utilized

Help the dryiads out a bit because they got nerfed too far from before.

Try to get people to play the orcs more.

Here is the patch log:
