The vehicles were so damn overpowered in Halo 3 and invincible to literally anything that there weren't enough lasers on maps.

I haven't played against enough vehicles yet, since I usually die by another heavy weapon before I can even do damage to the vehicles, but when I was driving in them they did feel like they take damage easier. Well, maybe they don't take damage easier, as more damage is inflicted on them...

Invasion needs to be faster paced.
