WoW's Shadow Priest

If you're a little more Darth Vaderthan Luke Sky Walker then the Shadow Priest may be right up your alley.

Really, it all depends on what works best for you. How you desire to play your character determines which character you make and which path you follow. Well duh. Most people don't roll Priests for the massive damage dealing and killing capabilities, but some do, and if so Shadow Priest is the one for you.

Aspiring Shadow Priests should understand one thing, even if you have shadow form and all nice damage spells, sometimes you actually do have to heal, like when in a party, or you're about to die, the holy and discipline tree's do exist for us dark siders.

Finally, not all endgame guilds, dungeons, etc. require shadow priests, obviously we bring some things to the table, but don't count on that spot not having been filled by one of the many already existing 70 priests who've gone shadow.

That said, here's a shadow priest guide that'll get you started on the dark side and give you a good idea of the gear you'll need to get, but if you want to rule you'll look into snagging a the Killer Guides' Priest Guide.
