Giving this one a test drive.
Quirks so far:
Dun Morogh:
Does not always vendor in the starting area. sometimes it did, sometimes it kept on running back and forth between mobs and loot without figuring out it should empty the bags. Guess this is just a problem with HB and not the profile.
(Edit: Was a problem with quivers, once i got all bags it was working)
Keeps running to the island with all the wolves in Dun Morogh. Repeatedly getting whacked down by 3-5 wolves. Rinse repeat.
Think this is since it passes the entire lake in one go, and the path is through the wolves.
The wolves right next to khranos is also a pain(huge aggro range. Pull one and the rest will follow).
Does not buy the beer for the quest where you get the dwarf guard drunk in the khranos inn, cellar floor - then steal his barrel of booze. Instead it walks up to the barrel and tries to complete it without the barrel being "active".
Might be an idea to blacklist that questgiver.
Does not know how to complete "Frostmane Hold". Needs to be blacklisted.
Other than that it's just LoS issues and 1-10 as a hunter sucks balls(no pet. adds = death).
The lepper gnome area was a bit of a pain before level 10. Hand grinded to level 10, got a pet and it was no problem.
Loch Modan:
It's basically a KILLER/wipefest.
Picks up way to high level quests, or quests where mobs are pulled in large packs.
IE, At level 12 picked up the 22 elite quest in the lake, gather tools quest for the gnome on the east side of the lake(Pull one level 15 mob, 2-3 adds, die, rinse repeat) then the Level 18-19 ogre camp quest at level 15.
Keep pathing into the elite horde pack that patrols the east side of the lake.
Has yet to pick up the "easy" grind quests in the logging hut far east, but this could be because it is still struggling with the ogre camp and keep running back there to die.
Will post again once it has been tested further.
Edit:
Oh, and it sometimes stop after talking to quest NPCs. Not because of pathing. It just stops. Not at the bot pc right now so can't give the exact log, but the last event was something about a gossip dialog. This i'm sure is not a problem with the profile, but a flaw in HB.
Info gathered onver several days:
Loch Modan(continued)
Does not know how to complete Algaz Gauntlet(picked up in northeren Loch Modan where it's supposed to kill orcs in the pass to Wetlands and "discover" the first area in Wetlands).
Wetlands
It's as if it doesn't even notice the murlocs north of Theramore. They don't appear in the "Targets" window of HB untill they actualy aggro.
It even was on the quest "Claws from the Deep" where it is supposed to hunt murlocs, yet it never pulls a single one on purpose - and only kill them when they aggro. Looks very awkward.
Other than that i had alot of strange mesh problems. Seems i was just unable to download meshes for a while. Got that fixed by making a new grind profile and mapping the hotspots to the quest areas.
(After the mesh files were downloaded the bluegrill murlocs didn't seem to be a problem any more. Could be related to not being able to download meshes - Need someone else to test that out since I have completed the quest now)
Either way... Got killed about 10 times in the mosshide area when it ressurected too close to the camps. Should add a blackspot over the "hubs" even though they are quest mobs.
As in, make it circle the outskirts of the camp for single, double or tripple pulls instead of pulling the 4-10 mobs at the centre areas. They tend to run away and pull even more so it's a death trap if the bot manages to wrangle itself too far into the camps.
It picked up "The Third Fleet" from "First Mate Fitzsimmons". -> "Unable to obtain enough information to complete quest: The Third Fleet - Blacklisting!"
I went ahead and bought the beer for the guy(poor sod

) and it turned in and accepted the next quest.
Had massive pathing problems in and around the ships where it needed to kill the undeads for "The Third Fleet"(part 2).
Might just want to blacklist that guy all together, since currently it causes more deaths than it is worth.
Did complete the quest manualy though, so will have to see how it continues the chain.
Left it on over the night. Was disconnected when i woke up. Logged on.
Restarted it as i went to work. Saw it pulling some mobs, so figured all was good. Came back from work. Disconnected again but also dead.
Neither of the logs showed anything out of the ordinary apart from a multipull on the last run.
Started it up and checked what was going on.
Not related to profile(HB bug), but just mentioning it: Trained a new pet, a crocolisk the day before. Then whenever the bot entered an area with crocolisks it targeted the pet and tried to "Send Pet To Attack!"(irony much? ^^).
Either way, the past two sessions it had been staring at the pet, either untill it got attacked by mobs and died or untill it DCed for being AFK.
Changed to another pet and restarted.
Have been having all kinds of strange meshing problems today. Especially in the Orc area(where it is supposed to collect warbanners). It just won't download meshes for some reason - or the meshes it has is not on par with the questing areas(could not generate path etc).
Manualy completed the warbanners quest and started it up again.
DC due to server restart. Will post again later once I have done some more testing.
