I have to say it's OP. Reason being, you don't start with anything that can kill it. Most people can't snipe good enough to even try to hit a moving target. It has unlimited ammo, it maneuvers very easily to avoid damage. You cannot board/hijack it which made Halo more balanced. Also, rockets do not lock on and move so slow these can also be avoided. All you can do is either: A. Wait on heavy ammo to drop if you have a rocket launcher. B. Camp out in a turret C. Hope your whole team rallies and shoots it together. D. Be good enough to kill the driver with a sniper rifle. They need to do something to balance the vehicles and fix the pulse rifle which does nothing in multiplayer.
