Hi ! Main AB here.
I started in the game as a Priest too and I was lucky because I found some people who helped me to be +85 and do gramps later.
But you NEED help if you want to get AB. Priest is one of the slowest chars to lvl up because it can't kill anything but undead. From lvl 71 to 85 you might need a party in Juno (Harpies bb) and then Wraith and Evil Druid bb from geffen in Glast Heim. Then is just party in Gramps untill rebirth and repeat the steps.
Is better if you just party untill AB and then still partying. All the parties need a healer and you are the one for them.
Good luck ! Because if you don't want to party, you need a loooooooooot of patience.
