Absolutely. While we're at it, let's get rid of 'nade launchers too. And silenced weapons. Screw it, let's get rid of everything and make everyone stand still lined up against a wall, unarmed, for the "I don't like dying" brigade to pick off at leisure.

Sorry, but I get pissed off with this same old question being brought up time and time again. We all have a pretty good idea of what classes are going to be available when we buy the games (or we ought to before we part with £40+), so complaining that you haven't figured out how to counter them is a pretty pointless exercise surely?
Operation Flashpoint, for what it's worth, is probably one of the better FPS's out there for balance and whatnot and is criminally under looked IMHO. There are still snipers and toobs in it, but it's not as arcade-ish as your MW2 stylee-games and the balance is far better for it.
