The design of the helicopter supports in this game I feel are quite poor. The amount of skill required to use one effectively is zero, and the overall feeling of the player who called it in is that they didn't do much. This is pretty annoying considering how devastating and they can be to the insurgent side, and very frustrating when you get spawn killed by one. I feel that helicopter supports wouldn't be so bad if they were at least fun to use for the side calling them in, but they arent. About the only enjoyment I get out of them being around is seeing them crash when they get shot down in coop play.
TLDR; They are fun for no one and should be out of versus play.
(Also wouldn't bother me to see supports cut altogether, but thats for another time)
