Nowdays we can do airstrikes in almost every server, which I like. The problem is idlers aren't just dead slots and a source of imbalance and easy points anymore. They enable the enemy team to make grenade rain and replenish ammo and health much more often.

I've exploited this situation to the point it doesn't seem fair at all but, why shouldn't I shoot at them and call airstrike support over and over?

I suggest adding the info "time played" and "time idle" to the score board, so it's easier to votekick idlers, and a configurable anti-idling system for server admins, which was dicussed time ago. ( http://ace-spades.com/forums/topic.php?id=1974#post-23476 )

"Watermelonbluntwrap" stopped playing, as you can see thanks to the "1 (minute)" under his time. I was watching to it, so I joined to balance the match.
