While the trust's way of reacting to that mechanic is a bit wonky, I'm not sure if it's a bug. They generally have a preset of spots to walk to during mechanics.

An easy way to work around their behaviour is to just let them pick a tether first, before picking one yourself. Always worked for me, back when I spammed those dungeons to get my trusts to 80.

The bug that I'm seeing is that they don't go to the same spot, relative to the boss, on any consistent basis. I'm trying to guess where they'll be so I have time to get a combo in before moving. I don't know why they don't just go to the closest tether to them when the adds spawn.

They don't always move to the same spot. As a melee, it should be fairly easy to adjust to a different tether.

That's exactly what I'm talking about. The NPCs aren't consistent in how they behave.

I always just waited until they took their spots before I grabbed mine. You have to base your movements on what they do first.
