Played for a few hours.
Non-tank vehicles are now worthless... I happily strolled through a meadow as a chopper gunner rained lead around me, but couldn't kill me. So much for attack choppers and blackhawks being something to fear... And why are the attack choppers so much more responsive than the scouts/light helos? Seems silly. The scouts will flip much more easily, but the attack chopper actually changes speed/direction much faster.
Jets only get their machine gun without perks. Right now, you basically fly around and look cool. If a blackhawk gunner can't hold his aim over me long enough, there's no way a jet will. The guns just don't do enough damage. Little birds suffer from the same issue. I've seen 2 kills from these 2 aircraft. A jet kamakazied a tank.
The maps are kinda lame too. They were definitely made for huge, 60 player games. On a 24-26 player game, they're WAY too big and you do a LOT more running than gunning.
I can't speak to gun balance, since I haven't unlocked enough of the weapons (or fought them) to give fair judgement.
