Neither, unless by campers you eman the tards on my own team, who sits in the base, instead of trying to complete the objectives needed to win the match.
I do hate several other things though.
Cheaters.
Peopel who call every player who's doing well a cheater, cause he canøt tell teh difference between him sucking and someone else cheating due to too much ego and toolittle skill.
People who, as mentioned above, doesn't try to play the mode, but just camps their own spawn, when they're supposed to go plant a bomb or something.
People who whine and calls people n00bs when they use a valid tactic, like camping their own bonb-spot when the other team is coming with the bomb. I mean, seriosly, when i'm playing demolition or search and destroy, or a bomb map in CS, and people whine about the defending team camping all i can think of is: how the fuck is our team supposed to defend our bomb site, if we rush to the other side of the map like some people think we should cause otehrwise we'd be campers. Or if the sides are the otehr way, why would i do anything other than rush, if i'm supposed to plant a bomb. I gotta do it before the other team organize their defences.
People who whine about every otehr weapon/tactic beeing overpowered. "Launchers is for n00bs" "gay camper" "rusher fag" "akimbo retard" "sniper scum" "fucking thermal scope" etc.
Theres usually a valid counter strategy, but people are beeing too retarded to realize this.
If people use tubes, use a blast shield to prevent some of the damage. If they're camping, just launch/throw some explosives in there and kill them, or go some otehr way around, if they're using akimbo shotguns, kill them before they get close, cause they can't hit on long ranges, or use a shield.
If all else fails, use the same weapon as them. If they haeva n00b tube and you do, and they're still kicking ur ass, then it's prolly cause they're better than you, so stop calling them n00bs already, cause they're betetr than you.
People should generally concentrate on whining less, and start worrying more about their own game, than that of their opponents. But i guess people are a bunch of spoiled tards, who can't do shit but get butthurt and angry, when the enemy doesn't pick weapons and tactics taht fit their playstyle, like they think everyone else is just there, to cater to their needs.
