To me, protoss seems pretty op. Terrain has lost goliaths so they have only marines for anti air early on. Zerg units are weak in general and you need to use the kamikaze units to do damage to ground units. The protoss phase-in ability is great for the backdoor slaughter. I still dont like that if you get dc'd, there is no way to get back into the game, but if your partner drops, you control his units.
