Pretty decent. I let it run for 6 hours last night so that I could get up to 525, and woke up to a 300g repair bill. Bot had been drowning itself over and over again. I find it is best to just watch it to make sure it doesn't do anything stupid.
Turn on the Rez at spirit healer option so if somehow you get in a situation like that it should not happen over and over. At least that is what is working for Kalimdor.
Also so far have gotten over 3k plus nightelf fragments(have all rares) 1k fossil fragments. I just want to get that tolvir mount allready lol...I guess making it go to a specific race when it pops up would be nice but wouldn't that just be more travel time?
