Please don't because all boosted players I've seen are terrible. The worst was a prot paladin who knew nothing about tanking. He didn't activate a Seal or used Holy Shield so of course he couldn't hold threat for the life of him. I swear I could see his animation jitter like he's spamming right click. Do yourselves a favor and level from 1-58 so you actually learn how to play your class.

Seriously though, you are right. I've never cared for the idea of boosted characters. There is a reason why the game gradually gives you abilities... so you can get used to it and learn how to weave into your rotation.
