I'm tired of yelling in proxy to back away from a tank because I planted a satchel, only to get team kills anyways. That or planting it, and then the tank purposefully drives into the team forcing team kills. I just got kicked from a match because a tank about 50 or 60 meters away from the team decided to kick it into high gear after being stationary. There was nothing I could do about it.
Basically, blueberries are stupid, and tankers can use the mechanic maliciously, and all of the blame gets put on the person who planted the satchel.
