It is fair. Just as fair as when I try to play CS or DoD:S and get slaughtered by someone with 10000000 bucks to my 100, or the guy who got the 'rocket' slot because the host is running a class-selection mod.
Wait, lets look at that a minute. In a game where classes are entirely open, there is a very popular set of mods that *restrict* those classes! And...and what's this? There is no 'high score gets first pick' mod to go along with it?
Why...I do say I think we're on to something here...
Shorter, less sarcastic answer: It *isn't* broke. Do what everyone else has done since the mod and deal with it. You can do that by a) checking the class list throughout the game; b) go out and take the weapon you want from the field. It's that simple.
(and damnit, I was ready to go off and carry this on for a half a page, but my bloody phone rang after b)
)
