Boats are pretty powerful when they have someone repairing. However, once you get your own boat and unlock TV Missiles, they go down insanely fast since you can fire both TV missiles pretty fast. One of my first 2 games had an attack boat and I used it. Went 24-0 or something because no one had anything unlocked for it lol.
How has the transition been going for the M/KB?

My only complaint with the game so far is the fact that Air vehicles don't get a warning half the time. They just randomly blow up or nosedive after being hit by a heatseeker or stinger. THEN once you've been hit, you get a lock-on warning. -.-
