Hello. I want to buy BF3, for play with my friend on weekends, but i have some questions.

1) How bad is hackers/cheaters situation? are the admins/mods active online? report system works or is useless?

2) Are jets/planes too much op like in BF2? is there any portable weapon (i mean that a foot soldier can carry) that can take down jets/planes?

3) What servers do you recomend in North or South America?

Thks for ur time
