The easiest way for me to avoid being shot by a BFG blast is to play on a server where the BFG is disabled. I hate that damn thing. Fiend, I think that editorial on camping and whining is one of the most practical gaming editorials I've ever read. People like to hold grudges in games which, in my opinion, is silly. A game is a game, play it.
Camping is a skill that can be used effectively in a game.
To those who think that, grow up. No one person owns the gaming world and can proclaim that camping is not aloud. I've seen a ton of crappy, skillless newbies camping, although I can see some instances where it would be useful. I know exactly how these guys are since I am in an action quake clan. If you have ever been in a game of action quake with that circumstance, be ready to sit there and beg for one of them to move.
