Zygor Guides is having a 50% off sale today – there really is no better addon for leveling alts quickly and efficiently from 1-90. You can buy just the leveling guide, or additional guides in various categories covering all aspects of the game, such as dailies, professions, pets and mounts, and reputation grinding.
From Zygor’s website, here’s some marketing copy that I think describes it pretty well:
Zygor Guides is an in-game software strategy guide for World of Warcraft. Every guide comes complete with the Guide Viewer, which displays step by step instructions of what quests to accept, how to complete objectives, when to use items, and more. Our gorgeous waypoint arrow will point you exactly where to go at all times and the model viewer will display fully rendered 3D models of NPCs and objects mentioned in the guide.
Zygor’s Leveling Guide includes the most optimized questing path for power leveling from 1-90 in lightning speed. The guide software is very dynamic, tracking your progress, detecting when you complete goals, and automating tedious tasks such as accepting and turning in quests. You will be amazed by the difference Zygor makes.
I can attest to the fact that the optimized quest paths are superior to the free ones like Jame’s leveling guide (which I used for my first main). I used Jame’s to get that toon to 85, and switched to Zygor when Pandaria came out to get to 90 and there was a huge difference. I’ve used Zygor since for all my Alliance toons. To be honest the guides are expensive, so I can’t recommend buying them at full price, but at 50% off they are definitely worth the investment in time saved.
Here’s a video that gives a preview of how it works:
I can’t recommend Zygor enough if you play WoW! There’s a free trial option so there’s no risk in giving it a whirl.
