I personally just want to buy a manual and fly. I don't want to complete all the content there is, especially because it's not relevant content to my toon. Just a boring snooze fest that means nothing. I just can't be bothered doing it and I will probably end up not flying at all in Draenor because of this.
Anyone else who just can't be bothered doing the achieve for flying? I really just want a vendor/trainer like in previous expansions. Worked fine.
