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.
I've been having what is apparently a scaling issue caused by inflated secondary stats on some Wrath of the Lich King items. In particular, my Highmountain tauren warrior leveled through Northrend and picked up a green, iLvl 87, 2h sword. All of the secondaries were in the +25 to +30 range, and the Dugi Gear Advisor decided it was better than the heirloom 2h axe I was using. So I went ahead and equipped the sword.
If you just want the short version of this review, Zygor Guides are the best WoW leveling guides. Period. They’ve been around since 2007, and are always kept up to date and improved, and they have tons of features that set them apart from the competition, not to mention a streamlined leveling path and slick user interface. It’s no wonder that they’re the #1 best-selling WoW guides, because they’re simply the highest quality. Updates are typically released in advance of major patches and expansions.
Workaround as a player is simply to skip forward past that step in the guide, at which point it has steps for the other quests. I'm still on Bleakrock as that character, so I don't know if a duplicate "begin the evacuation" step exists after you've found all the missing people. In either case, just don't talk to Captain Rana about evacuating until you've completed all the other main/sidequests on Bleakrock, which are listed at the UESP link above.
