Hey guys, DesMephisto here and I’ve been hard at work creating routes for horde and alliance to level as fast as possible. My most recent 20-120 was done in 23 hours 17 minutes 20 seconds for Alliance (In one sitting). I’ve partnered up with Azeroth Auto Pilot to get all these routes out to everyone.
