I have tanked in several different expansions, and some mobs always hate when you get a little too close and they will back up; it has always been that way… but in Shadowlands, there are mobs who will constantly pace back and forth, even if your character isn’t moving at all! I haven’t seen anyone talking about this, so I just assumed I was being delusional, until I ran a timewalking Halls of Lightning and decided to experiment.
I was tanking Ionar and decided I wasn’t going to move, not even turn my character. I initiated combat, got into position, and stopped. Hands were off the mouse, only pressing my hotkeys for damage. Ionar moved so god damn much after about 15 seconds he ended up behind me. I could no longer hit him or block any attacks (obviously I turned around and started doing my job at this point).
So something changed in Shadowlands with hitbox detection, or something, that is causing mobs to move around a lot. I thought it was just Shadowlands mobs being weird, but after seeing older enemies in Timewalkng dungeons, it is everywhere.
Please stop giving the mobs sugary soda before I run a dungeon.
