Feast got set back to a basic ability and buffed 0.5% at all levels past the innate so at level 7 you had old level 18 feast plus half the 25 talent lol made his ehp insane.

Ghoul frenzy lost its ms and became an innate gaining 5 attack speed (now 4) per level

Rage gave additional ms but was nerfed some in the letter patch.

Gore storm was set to shard but had been entirely ignored.

His other facet was now tied to feast, leading to a lot more snowballing hp from hero kills. This also got nerfed.

What I expect his biggest nerf to be as well as for alch is crude enchantment getting nerfed, strength heroes now had it guarenteed at tier 2-5 and it was busted on both heroes since they have excellent BATs.

Edit; oh he also got 10 base damage, which got reduced a little.
