I’m only playing oceanic official servers, all I tried are the same, it seems quite simple, the thralls instantly return to you as soon as you leave their render range, this may be intended to force them to follow however if this is the case its a disaster for me, I have lost some thralls already due to it as the mounts in particular find alternate routes sometimes if you for example climb a ledge to look around and get too far away from them and aggro everything along the way and drag them directly to you, the fighter thralls on the other hand teleport directly to you which if your invisible amongst a crowd is REALLY bad. If thralls are now forced to return at render range this really needs to be disabled at least for hold command imo.
Also I’m finding thralls don’t attack the new hunted mobs it seems, I have been killed multiple times as they don’t target them at all, even when they get hit in follower aggressive setting.
