I don't like the Tanks.
They seem clunky, hard to steer. Cross hairs are way too thick, amateurish. And worst of all... I CAN'T SEE BEHIND ME!!!
Proximity sensors + thermal optics = win
My biggest grip was the ability to see but this now gives me hope that the unlcoks will resolve that
Oh - and the TOW or whatever AT weapon the LAV has is deadly! I'm loving it - Hit the tank with the TOW, switch to cannon, fire off a clip or two and then switch back to the TOW. By now it has re-loaded. Fire again. You only need to hit it with the cannon a couple of more times if you get it from the side/rear to destroy the tank. It's easier than using a tank to kill a tank!
