People HAVE to gang up on vehicles, if not they get desimated.
Again, anyone thats isnt an engineer is basically a free kill unless you suck enough to get c4ed.
I can jump in anything and get atleast 5 kills before I get blown up.
A nikka could also die 5 times trying to take out one vehicle.
I get your playstyle but you admitted that you never ever play on foot so I dont think you have the experience to understand balance.
You just want shyt to be as easy as possible on your end, but the truth is that its a hell of alot harder to blow up a tank than it is to kill someone with tank.
As far as people gaining up on vehicles, this is a team based game, if your team isnt keeping you repaired and taking out the engineers then
