30mm from Bolte does less damage to infantry than 9mm from firearm.

Before yeah I agree it was devastating but now it's utterly underwhelming the purpose of battlefield vehicles is to feel powerful and useful but now it's more of a transport than anything. It's underpowered and is destroyed relatively easy. Makes you not want to use them as all since you blown up quickly. 

What I recommend is buffing the damage of the vehicle weapons such as the minigun, 30mm, 40mm, and 57mm, but small increments to be actually effective towards infantry but not overwhelming either. For example the minigun spreads way to much and it's lack of damage makes it more of a closeup weapon but then you make yourself vulnerable and quickly get destroyed by infantry. 

Like the 30mm on the choppers are just bad against infantry now, it takes a whole burst of the gun just to kill one infantry and if you are lucky and they closely clustered together like 3m within each other you may get multiple kills. That is if your pilot is steady and not moving to line your shots but then you are vulnerable and the overheats to quickly for a good support weapon either. 

Overall at lot of vehicle weapons need another rebalancing not saying make then overwhelming powerful but more efficient since there is way Kreme infantry to destroy you while the vehicle is underarmoed to survive and the weapons are are not strictly strictly enough to get a flew kills before getting completely wrecked by infantry.
