I think part of the issue is that a lot of those guides are outdated. Blizz I think streamlined unlocking the ARs thus making the guides sometimes point people to the wrong quest giver. Also sometimes it just bugs. Like for example on one of my toons, whenever I go near the FP in Boralus, Tinkermaster Overapark and his assistant always spawn and start a dialogue. I know it’s in relation to unlocking mechagon but after they do their RP, there is no quest. Nothing. So a returning player will just sit there completely at a loss as to what to do.
Recently I had to install the BTWquests addon and it’s been a godsend. The addon gives you a searchable database with clear quest chain flow charts that tell you what you’ve done and where you’re up to and what you haven’t done. It’s this kind of UX design that wow sorely lacks. There’s just too much obfuscation sitting between the player and their goal these days.
