I tryed to play Medal of Honor over internet, and i found on a 32 players game, at least 5 or 6 players with bazzokas fragging everyone in sight. Bazzokas make all kind of games Quake 3 style.
Damn, I didn't think that could happen in a real mod. Normally, I would think that an m16 would pick you off before you got the chance to go Q3 style, since the reload time in RL is so slow.
Ok you could change your should be able to change your main weapon but only from a list that ties in with the role you have chosen.
That could be advantageous, but I think one of the things that the team stress about Inf in the info sections of the site is how Inf has no role-playing elements- ie no class system; if you wanna be the team sniper, then you pack a PSG in your loadout. If over-powered weapons do get implemented in Inf, then they may change their minds, but untill then I'm guessing they're pretty into the non-rpg element of Inf.
Anyway, I don't know much about real RPGs, I was just thinking it would be a good alternative to the grenade launchers, since it travels line of sight instead of lobbing. If the cost would be an issue, then they could just do what they did with the PSG-1; make it really f-in expensive. That would also be a good way to enforce team "roles' without resorting to a class system. If all you can carry is an RPG and a sidearm, then most people aren't going to use it unless they really need it, and they aren't going to go Q3 style because they won't be able to afford using so many rockets.
