I already said this multiple times on various threads but what I wish exploratory content to have is more avenues of progression.

Having various quests to do (and not just milestones for it like we had for Eureka and Bozja), have gear rewards from special world bosses or dungeons you can access and not just something you acquire near the end, allow crafter and gatherer classes to contribute with zone resources as well as partcipate in timed zone scale events, have the zones be bigger and less aetheryte convenience and just overall be less of just another flavor of Fate train spam because thats 90% of current exploratory zone content.
