The point he's trying to make is, these aren't noobs who are trying to learn the stuff. They are just assholes who take the armor, park it on some hill somewhere and camp in it, not providing any kind of support for their team or allowing anyone else to use it.
It's just like the assholes who take a plane/heli and use it as a taxi to get to a capture point faster, bailing out and causing it to be destroyed, therefore depriving the team of that asset.
There is a difference. And believe me, you can try to chat all you want to people in-game, rarely will jackasses like that reply to you at all. They know what they're doing, and they're just doing it to be dicks.
I've never come across people doing that. using helis as taxi, sure and that can be annoying (only when I'm in it and they don't tell me)
But I've never seen people camp armour far away from the battlefield and just sit there. This must be an entirely new thing in BF3. One that I have yet to see.
But it's a multiplayer game, you have to expect that somebody somewhere is going to do something dickish, because somebody somewhere always does. Just keep on playing the game, squad up with people who aren't assholes and ignore the retards... If it's so prevalant then someone on the other team is going to be doing something equally dickish.
Tking is not the answer, tking is fucking annoying.
