Just a suggestion, or maybe there is a reason and someone explain it to me.
When I place a anti personal landmine on defensive location and a teammate steps on and dies, I own -2 points from my score.
I think it's unfair that I pay for it (or only me). My teammate should be more careful and in this case should at least share the blame. Some players step on land mines on purpose to hurt score of other player's or only for annoy.
I propose that instead of subtracting two points to the owner of the mine, subtract one point each, or just to the careless player.
Thanks for read my bad english!
