I think a better way would be to add a low ranking penalty
A true casual person may not care about this kind of punishment
But it can very well reduce the number of spies or anti-intellectual groups that are more passive in fighting.
Yeah, I get into a plane when things are stable, and before I can make a run and reload, everything starts going to crap and by this time it’s to late to bail out and get to the control point before it’s gone. I’m not great, but am an above average player, but I am constantly yelling at my computer that I can’t do it all guys, I need some f**king help. 
Every close game I play that I lose seems to be because of people NOT trying to capture or defend control points. They instead choose to wonder the valley looking for another kill. I always say, close games are decided by which faction has the least amount of stupid players.
