I for one had no issue with various fetch quests or aether flight unlocks

Use that guide to save lot of trouble in the future. You should not do every quest available before you can fly. You will just lose your mind by doing so. Just a few quest here and there and the rest when you can fly.

Again, level locks. Doesn't matter if you know which ones to do. They are still locked away by quest level. If it was JUST the aether currents I'd be less annoyed about it but still annoyed. Aethers tied to quests so they can level lock the flying is dumb.
