The other week Mahisha spawned and was reset at 5% with pretty much everyone in the area dead or weakened. No one was even asking for a reset, now that is a grief.

The way I see it. You reset a mob with an intention to help others, you can get banned. You reset a mob because you had to ran away to avoid dying, you should be safe.

Some mobs are dangerous to reset anyway, like the Sabotender, just don't follow the person attempting to reset, they'll die to 10k needles in no time.
