I have been using Zygor’s Guide for the last couple of days and I cannot believe how awesome it is.  I had briefly checked it out when it first came out, but everything they have done with the add-ons are amazing.  There is an on-screen step by step guide that walks you through every quest in the proper order.  If you can read, this guide will work for you.  If fact, it almost levels your characters for you.  I truly believe when they say it will get you to level 70 in under 6 days.  I am already level 17 and I have only been playing for 12 hours.  That even includes me taking a couple side trips to Org. to visit the auctioneer.  I probably wasted 30-45 minutes.

I haven’t had a lot of time to play lately, but I hit level 50 at 4 days 30 minutes played. I was hoping to make it in under 4 days, but it didn’t happen. I’m still very satisfied.
Have you been wanting to re-roll a new character?   Zygor’s Guide makes it so easy to get your character to level 70 with minimal effort.  Best of all, this guide is for Horde or Alliance and any class.  You don’t have to be a hunter like some guides.  You can be whatever class you like.  I strongly recommend checking them out.  It is worth every penny.

EDIT: Ok - I’m up to Level 36 1/2.  I haven’t just focused on leveling.  I wasted some time messing around in the AH a couple times.  My /played time is only 2 days 6 hours.   I would say that about 7-8 hours were wasted on other things.  This guide rocks!
