Skip the looting. On my way to 70 I looted everything and skinned everything skinable. You get the loots, but it does slow one down. If you dont need the loot or skins then skip the looting. This is interesting because I am not the fastest leveler in the world. I got my Rogue to 70 in just over 15 days time (using Joanas wow powerleveling Guide,) which is Ok, but its not breaking any records. So here are a few things which slow me down, besides lack of wow powerleveling experience, and what to do instead.

 

Let your mule do the buying. You should have an Auction House Mule. This is a low level character that will live at the AH 100% of the time. This character will do all of your buying and selling. Never visit the Vendors, except to resupply, repair, and sell your grey stuff. Everything halfway decent gets shipped to your mule. Your mule buys the gear, then mails it to your main character. You will save plenty of time doing it this way by wow powerleveling. Your main should never visit the AH.

 

This assumes that you are leveling solo. Skip the gathering and gold grinding. On your blast to 70 you might want to be as ruthlessly efficient as possible. Besides, if you follow the gold blueprint you wont really need to gather. Just kill and move to the next. You will save a lot of time over those 70 levels. Skip the PvP. If you are on a PvP server just put up with the ganking you will get and move on. Keep yourself in decent gear. By decent I am talking about gear for leveling, not raids or PvP. Green gear will do you fine. Upgrade it every 10 levels or so.
