Tanks strange behavior

Had 3 dungeons each yesterday and today. Six full runs where they all pulled with melee attacks, only did one AoE, and proceeded to single target the rest of the pack. A single pack at a time. With no mits at all.

I was running with other people who don’t feel comfortable tanking as DPS and loot timers were always rolling. Yes, we could have waited out the timers, but there was always a longer wait than it took to clear the next pack.

I did ask the last 4 about stuff, like no TBN (at 80) and about the lack of AoE and no other mits, but radio silence.

I am aware there is a Mogtome event, but this was just bad. Play on Console, so no screenies to go with. Just needed to vent a bit.
