I have a problem, that'll probably be an HB bug, but... you may know for sure.
I've noticed this at every level and with every profile. The bot keeps pulling mobs that are WAAAAAAAAAAAAAAAAAY out of range, often ending up pretty far from a quest's area.
For example, I was just observing this quest in which you have to go to all of the Arakkoa camps, go up towers and kill a named mob, but the bot was grinding here for over an hour
until I decided to kill the mob manually. It was constantly clearing the ground level, and since the mobs kept respawning, it'd never stop. But when there was no mobs in sight it'd just go run
60 yards just to find one, instead of carrying on with the quest.
I'm pointing this example out, but like I said, I see it all the time. Not ALWAYS, but very very frequently. Bot will be on it's way to somewhere, run into mobs, dismount (before they even aggro)
and pull them (even when they're further than the pulldistance).
Anyway... I don't remember this from before the patch. Do you know if it's a known HB issue?
