I find it really easy to abuse restricted areas in order to bypass players on the opposite teams and blowing out their cache. This is so useful in skirmish. But is it fair to be able to do this, should there be a kill timer so players don't go too far like I did. Or do you think players just need to be more aware of the map and protect their cache better? This video should help you decide (and I also got stuck in a pipe after the middle mark, that was weird xD) :
