Talents are re-learnable. I find that a lot of new WoW players are soooooo afraid of putting in the "wrong" talent and are obssessed with getting the perfect cookie cutter talent built.

This is not RO, you can unlearn and change your talent builts. Yes you do need to spend some gold but so what? The first few changes are affordable. The talent builts are not "one size fits all". Build it to your playing style, that's what makes this game so good, you can kinda make yourself unique. Experiment.

Just learn the game as you play, read up on guides if you want the quick way out. You got heaps of resources from www.worldofwarcraft.com. Read up on your class forum and/or profession forum. Although I don't believe there is a "wrong" talent build, but there are some "stupidly allocated talent points" build :b
