Hahaha, yeah, the teamwork is the best part of this game... when it's working right, anyway. PR really forces the "work together or LOSE horribly" thing.
I got in an argument with some of those fanboys one night...
Me: These rifles are horribly weak. A burst in the chest from an A4 is gonna put someone down.
Them: Nuh-uh! 5.56 is too weak! 5.56 sukcs!
Me: Let me guess, you'd not think twice about trusting your life to a .45?
Them: A .45 is a stopper! 5.56 isn't!
Me: Um... Go check out the differences in rifle wounds vs pistol wounds sometime, would you? Rifles>pistols, noobs. High velocity bullets tend to shred stuff, man.
Them: Nuh-uh! 5.56 is too weak! 5.56 sukcs!
I forgot to add: the beltfeds ROCK! Finally, the SAW and similar weapons are something to FEAR. Ditto with the grenade launchers. You should be VERY afraid of someone with a 203 who knows what he's doing. I racked up a crapload of kills on Mao valley with one. Nothing's better for clearing jungle than 30mm or 40mm HE.
