Overhaul the tank by separating duties, reducing the total amount of tanks to 1, buffing the tank a lot. Currently the Humvee and Quad are extremely fun because they use actual VR controls. The tank should be the same way, however doing so would require separation of the main gun and driver into two separate jobs. The game Pavlov is a really good model for how a tank should work in VR. However, I think the tank in forefront should drive similar to the Humvee with a steering wheel rather than with sticks. Making the gunner reload the cannon after each shot could be fun but an auto loader would also make sense as it is a modern/near-futuristic game. With this overhaul, the tank would no longer be third person and would require a bit of communication to be effective and this is why it's armor should be buffed as well as it's damage output. It would also require 2-3 players and if buffed with an effective crew, 2 tanks might be overpowered or use too much manpower and hurt the frontlines and this is why there should be only one tank with this overhaul.
