Hi,
We don't have anything against the brain use. It's sure the game will be really interesting if someone could use his own brain on the battlefield !
Indeed, if you hear someone near you, you crouch or walk, to avoid make noise. You hide beside a wall or column, and when he's visible, you shoot. That's an ambush. We don't have anything against this strategy in the game.
However, in these last weeks, the game was annoyed by abusive campers ! The kind of player who never leave his respawn, and play without any strategy. I think someone like Emiliano or Daggi, we all know where they camp. There is no surprise ! But that's really annoying ! And we estimate that's really a problem in the game. You run, you run, *boom*... Stupid, makes no fun !
Thus, i think you misunderstood what abusive camping was. We don't have anything against brain use, but we don't tolerate abusive camping.
Have a nice day
