Just started to use this, 1 lvl 90 (Hunter) and 1 lvl 10 (Pala - Retri). Doing Deadmines; actually working very well. The Hunter does need >10 minutes to clear all, so that's fine. Sometimes he misses a mob (or 2), and my follower dies. This happens every 3 runs or so. Not a problem per se; but the dead follower keeps standing at the spirit healer and my booster just continous clearing the Deadmines. My follower stays dead forever. I then stop HB, walk him in, start HB (follower walks out and in again) and all continuous as normal.
So far it works very nice, not AFK'able though.
I did make the mistake of letting my Hunter auto-use Feign Death. I can really not advise that, and you probably can see why

I can say though, that this is really slow compared to questing if you do not have RAF. The XP per hour for the lvl 10 is really low (I dinged 11 after more than an hour!!), so only use this while RAF'ed (triple XP).
Otherwise... way too slow. 22 xp per mob is what I get (not rested, no guild bonus) and questing is WAY faster.
Still, nice work and keep it up!
The main problem I have with this is with AutoEquip2. What a weird piece of software that is... my Retri Pala prefers gear with... INTELLECT... :/ "looted item does not have our primary stat of Intellect, so rolling greed".... REALLY? Retribution pala = Intellect? Weird stuff
