Solution to problem: boycott the map hospital, or forceclass away all SF maps to normal M16 and let the new players get the feel of the game, and not get shot by 12 people on the opposing team 203 spamming or sitting crouched/prone zooming on 1 spot for 6 minutes. Hospital has always been a popular map, and is the main reason people don't play other maps, hence letting the new players, if there even are any at this point. Play more fucking maps.
Flame me.
I tend to think beginners prefer to play with SF, seems pretty logical to me. It is a fact M16 require more "skills", that's why there is more chance beginners will get raped on a long/short distance fight with M16 because they can't really see the enemy or because they don't really know how to aim with it. Give them an SF and they got a big scope with even a grenade launcher, wauw.
Changing weapons won't attract players imo, but it could be fun indeed
