B6 vehicles

Does engineer need 6 RPG rounds? Does the stinger need to start with 5 rounds? Helicopter gets 1 tapped by stingers.  

Same with tanks. We have new fancy tank mines that dont even have to be hidden and mess tanks up. Overall vehicles survivability rate is extremely low. You can make an argument for tanks being ok with an engineer repairing. But so far in the beta I cant fly anything with stingers locking on constantly. Getting 1 tapped by one is also so frustrating. 

Enjoying the game otherwise. Its a new edition obviously a lot of changes. Wish we had bigger maps for the beta. Seems like these are smaller maps infantry focused.
