I know some of your frustrations even though I play more in the MMO space. And yes I sit behind the objective so I can laugh when they fall into our trap. It totally depends on said objective and the surrounding environment on where you want to be though.
Anyways, you do take it too seriously, it pissed you off enough that you started a thread here to complain about people who's play style/experience does not agree with your own. Have I gotten pissed at my teams performance? Yep, know what I do about it? I say Fuckall and go have some fun fucking with people like you =D at that point winning isn't the point, do you get my point?
These games are to be played to have fun, if you are not having fun then you need a new experience.
And camping? = Not fun, people get bored, sure I've been holding this objective for most of the game, but huh... look at the mini map, everyone's over there... (5 more minutes goes by) goddammit this sucks I have not had anyone to fight no one is heading this way, I'm heading to the action to go have some FUN. Even if holding this point will ensure victory, and sure as shit the second I take off some clown shoe will go and take it. Then the leet folk will shout why the fuck are you all at mid!? Because mid is fun!
I will also blame lack of any play ability on those parents that are getting their little tykes games they should not be playing.
I'm too old for this shit comes to mind. (I'm only 34) I have a buddy that's more into FPS's and when he does not mute all, wholly hell its an ocean of pre-teens screaming obscenities. Its no wonder they don't have situational awareness, they don't even know where their balls are yet.
Oh and yeah DukeNukem for the FPS win, I remember lugging my tower and monitor over to a friends place to have lan matches, ahh what fun.
NEEDS MORE TRIPMINES!
