I can’t speak for anyone else but I always do a first dungeon run with trusts. I like running through with trusts for levelling too.

One thing I thought was a shame was that trusts won’t follow behind you when you run away from them while fighting, meaning you can’t easily gather up all the mobs for a speed pull

I’m terms of how they engage I do agree it can be annoying that they stay behind you at all times lol. I’ve notice that there’s also a bit of a delay between the trusts finding the mob and actually attack them. I’ve found that if you get close enough to the enemies without aggroing them, tanks will then jump in and engage. Not that doing that is any simpler than just facepulling lol
