I personally like the currents and as someone who explores a zone and does every quest in it they’re something I pick up naturally. I do understand it’s not for everyone though.

Perhaps they could just unlock flying at the point they usually give you the last current. But I don’t see them letting you fly from the beginning of the zone.

Story content is paced the way it is so you don’t blast through it straight away and unsub sooner. Plus they use the lack of flying to keep you away from certain things and split the zone into both a level 60 and level 67 zone. So it’s not going away altogether.
