I do it cuz my golden rule is if no one dies and enemies die then idc how the tanks feel cuz ik for a fact dps don't care cuz all they want is for stuff to stand still and die fast. They don't care if ur hp while tanking stays at 80%+, they just care if u get it done clean and fast.
If tank gets pissed off etc then let them, these dungeons can technically be solo'd * takes a while/ lots of kiting * , duod or trio.
I also tell them they can afk till we reach boss so you'll at least be somewhat useful in the run.
