I discovered the first skill that you master in WOW is the art of dying. The problem is that this goes against the objective of the game, which is to make the other poor dumb bastard dye for his country (to paraphrase Patton).
If you're an experienced first person game player the controls should be easy, what is hard to master is the dynamics of the games (understand all the weapons, armor, what to attack, etc...).
Like anything if want to become good at it, you have to practice, practice, and practice some more. If you want to get good at WOW you need to get ready to make the time commitment, otherwise you're wasting your time.
