For example:
Halfway through an upward lobby I need to leave to deal with an emergency work problem. Rather than being a dick, I !rep myself. (By the way, the new system sucks but that is a whole different topic). I then wait until a sub is on the way and the server kicks me so he can have the slot. In this way I have taken effort to ensure there is minimal negative effect on my team and yet my reliability rating goes down. Not really a huge deal but if its easy to implement I would like to see it.
