Hello. I am still somewhat of a noob when it comes to using the bot, so I had some problems handling the behaviours and profiles already present in the OP post.
After a little bit of looking around I decided to make my own profile and see if things work out. Here is the result. The profil will basically run around the whole Dustback Gorge area and kill Gorge Stalkers (the tigers) and Mushans. Skinning is pretty much a must have for this profile, since you will get tons of lether.
Right now I am using a lvl 87 Beastmaster Hunter with a spirit beast as my pet. Since the worst case you can have here are two of the tigers or a group of a major and two younger mushans, there shouldn't be much trouble if you have some normal Pandaria gear, since the tigers can hit quiet hard. I advice you to try it out though. My hunter has an item level of 400 (I have done a few instances to boost it a little) and he didn't die or even get close to dying once.
I can get between 1.6 and 2 million xp/h with this profile.
Another thing for skinners. It has probably already been pointed out, but it is a good idea to make a macro for using the Plump intestines you will get while skinning to not fill up your inventory with them:
#showtooltip Plump Intestines
/use Plump Intestines
I simply added a condition to the 'pre-pull' part of my hunter's behaviour, telling him to open a plump intestines, using the macro. Things work quiet well. There is probably a better way to do this, but for me it is working.
Feedback would be appreciated.
