If you can't file a complaint against a teammate whose mine you got blown up by, what's to stop jerks from constantly mining the crap out of places where teammates can't help but run over them?
You have a point, but still, the mines have to be planted outside and in soft soil, so you cant really mine a doorway that effectively. Also, if it's a mine from your teammate, you can see the flag that shows where it is, and if you look at your compass, it shows up as a big huge blip, bigger than 3 people clustered together.
