You can bug bosses as a hunter, if you got a melee-"run" pet, with Blinkstrike/kill command(only tried as BM).
with this you can "evade" bosses, or make them attackable for a few seconds, without anyone taking direct melee dmg(only @ starts, as pets cannot taunt bosses anymore).
How To:
Find a place, with a higher altitude than where the boss is.
Have MD on your pet, pull the boss, and if timed correctly, use Blinkstrike/KillCommand, and your pet will stand still + the boss will not move either.
Idk if this can be useful to anyone.
But this surely is not intended.
