As we are getting closer and closer to the lanuch of WotLK, some of you might wondering about changing professions, but you don't know yet which one to choose. With the release of Wrath of the Lich king, every profession will have a few profession only bonuses for level 80 players which are good for high end raiding and some of them for PvP, for example enchants and items that can only be equipped or used by yourself.
I recommend trying Zygor's Leveling Guide if you are still leveling your character or you just started a new alt. The guide is in a small window on your main screen in-game. All the detail that you need to complete the quest is included. You’ll never have to switch back to a website or even the in-game main map to see where you have to go or what’s next. The guide is available for both Horde and Alliance.
I use Zygor's guide for leveling, and I highly recommend it.
