If the Vets vs. noobs is treated in a fun tongue in cheek manner it makes a great game
Hicaps, lows, mids, real...that is never the issue (I'm guilty of the odd hicap for my truely lazy days), it's been already said, it is the playing style. Ammo restrictions (Scarecrow's ears must be burning by this point) are great in a high level sim game, but for an afternoon or day of fun skirmishes they can detract. The key is to teaching the spray and players into learning the value of trigger control. So instead of bitching, take the lead and offer them help in making their game better (when you are stuck with them on your team at a game. You wont convert them all, but if some listen, awesome!).
