Based on the discussions I've had here, I've made a video analyzing the vehicles to figure what's making them under or overpowered.

In short, damage takes the blame for other aspects of vehicle performance that let them rack up lots of kills, such as being too hard to hit or taking too many hits.  I've come up with solutions that would make each vehicle class more effective while making countermeasures more unique and interesting.  I focus mainly on vehicle vs vehicle combat, but I'll try to make another one focused on infantry anti-vehicle options if this one does well!
