No, I don't think you understand. A tank would get cut, or crushed, to bits by even the most average intermediate combatant. It's slow as hell, and its ability to aim ain't fast either. If someone can fly, the thing is even more useless, and if they can just keep moving out of its aim and circle in on it, they can keep doing damage to it while you sit inside of it uselessly.

Seriously, there's not much point in it.

@Koka: Edited my post to suit.
