In ARR and HW I always did every side quest that I could find and yet in SB a lot were open for a long time and I still have some left in Yanxia. If more sidequests were as interesting as the market ones in the Azim Steppe maybe I would enjoy them much more. But sadly they are often just meaningless fetch quests and only a few gems in it. And this comes from someone that enjoys the lore and story aspect of a game way more than the gameplay.
