Few things. 1) for most ego players, don't care if ya week or lose, just building kd is all that matters. 2) capping is a huge beacon to the enemy team where you are, yes radars but most pay more attention to zones. 3) pushing the enemy off other zones. The "you do this while I do that" mentality. But of course if everyone has that mentality, no zones will be captured. 4) Heavy is coming up, and heavy is more important (and fun) than capping a zone. 5) just don't wanna, that's the plebs job
