I was just killed by an ally who was intentionally trolling me with mines, trying to kill me. If you arent going to put in a punishment for that kinda of behavior, besides i assume some kind of slap on the wrist, then please disable that particular method of trolling.
I would actually be okay with them reducing it to only knockback effects. I know it can still troll but I feel some sort of punishment is needed for stray mines.
I think this goes into the high risk high reward thing though and it might make it semi-inbalanced to not do damage. Very often in every level of gameplay from casual to competetive does an ally mine connect with their teamate - despite the lack of purposeful intention.
I feel in this case that the real problem is trolling and not the mines themselves.
Which brings up your point about punishments.
You can mine an ally to death and it will count as "A Harsh World" death.
There should be punishment for shooting teamates or at least some kind of something.
But again, a troll will troll and a punishment for shooting teamates cannot be too harsh when literally the only weapon that actually does something is the mines.
Would it be fair if mines did not do damage or knockback to teamates? I really don't think so. I can't think of a valid solution to this problem except for maybe introducing the ability to replay games in order to better utilize the report system.
Why don't we have a replay system?
