So how do i go about queing for av do i just start it and bot will open it up and play / leave when its done and reque?
When you start HB, you will see a drop down box, the default entry should read 'Level'. If you want to queue for AV you select mixed mode AV. It will run your selected grinding profile while waiting for AV to pop. It will complete AV, then continue grinding while waiting for AV once again.
The battleground profiles are already present in HB when you download it. Actually, there are already grinding profiles present with HB come to think of it.
There are custom profiles for leveling 1-60 58-70 70-80 in the profile section of the forum. Take a look there.
