I’m still playing WoW Legion after returning 3 months ago – specifically I’m trying to see the story (meaning world quests, dungeons, and raid content on scrub level), and get the Flying Achievement. For the first few 5-6 weeks I didn’t think I cared about flying as it seemed a task for later, but now it frustrates me watching other players swoop in, complete something, and swoop out. I’m now 5 weeks into playing scrub/casually and creeping up on the farmable reps, and the (huge) zone quests in Suramar.
Legion Flying takes dedicated attention to get because it requires completing all the zone quests, considerable effort in reputation farming, and making sure you have travelled everywhere. Those tasks unto themselves are worth it because they help/force the player to see the content. I dislike how unfriendly to roadways and cumbersome some of the zones are (High Mountain is a disgrace). So Legion Flying is essentially very easy when compared to very difficult content like the Mage-Tower fights, however it takes a concentrated effort of many months when you play very casually.
If I get Flying, see the raids, and a second Legendary drop by the time the expansion ends then I will be happy. … In the pic blow is Mortigen wearing a terrible clown-suit leveling drops surrounded by a few ghouls (unholy spec), a bodyguard, and a quest follower.
