hmmm in relation to your reputation idea tech, it might penalize people who are, for example, playing at work, or in a situation where they sometimes have to leave a game early, to get on with their RL. How about it starts recording when the player has surrendered 2+ times in a row, and adds up each time?
Making it surrender twice: +1, surrender three times in a row: +3, surrender four times in a row: +6 etc... dunno if that makes sense to anyone else but me >.<
It'd penalize those who surrender constantly, and greatly penalizes those who surrender many times in a row

EDIT: just realised my post didn't make sense >.< fixing it now
