I's still learning to be a dwarf priest. At times it be all inconvenient-like.
But I has been finding some useful references. First off be a whole bunch of recommended talent specs at season 19, 29, 39, etc. over at WoWwiki.com. Includes variations fer PvE, PvP, and whatnots. Second good reference I picked up this week is a really impressives How to Melt Facesguide and flow chart fer shadow priests over at Dwarf Priest. Also has smites fer thems what insist on being holy. Is geared more fer endgame than leveling, but still most usefuls.
Edit: The Dwarf Priest were kind enough to gives me a link to a most impressive priest leveling guide she done put together a while back. So now me breakfast be complete.
