First: the hackers can ban anyone, not only who plays in pb servers, first.
Second: dice doesn't listen to the community. During beta they said it was already better, but no, it's worse. No more terrain deformation ? That was a big fail, and instead of fixing it they bring it out.
Then about mp: I have to say the truth, it's a joke. Still full of hackers (not only aimbots, there are also hackers with radar, no recoil hacks etc. which you can't notice and then what ?
ALSO WORST PART. Weapons are too unbalanced, SERIOUSLY ? They can track your jet, helicopter from ru to us base and you can't FLY.
