Before there was ingame WoW leveling guides, there was just eBook PDF leveling guides & what you paid for was the questing path. As far asWoW leveling guides have come with fancy ingame user interfaces, the questing path is still the core. Both WoW guides spend endless hours researching their questing path to find the fastest way to reach lvl cap. It is pretty hard to deem one faster than the other as both produce extremely fast lvling times. The reason I wanted to touch on this area is to confirm that both are really well planned and have seemingly very little difference.
Four groups of Zygons attempted to make Earth more like Zygor: those who arrived in the 12th century (TV: Terror of the Zygons), those that arrived in the 16th century and plotted to invade in the 21st century (TV: The Day of the Doctor), those that arrived in 1909 (PROSE: Sting of the Zygons), and those that arrived in the late-20th century.

I used Zygor for legion and BFA, used AA on an alt for BFA. Personally i like Zygors format more. I like being able to target things like achievements. I used Zygor to get my Mindworm and my Lucid Nightmare as well as finish the Rep grinds for the allied races. I have zero complaints. My experience was great. I also used Zygor for some professions, recipe acquisition, a couple mounts, all of the Suramar quest line. Thank God for that. And for the last zone of Draenor on my Demon Hunter.. i forget the name.. Whatever the big daily hub thing was called.
