Any talk about them doing away with Aether Currents for flight

Not likely. And if they did remove aether currents, they'd probably add some sort of alternative unlock method. It's just another thing for you to spend time doing to keep paying your sub.

Eeeeehhhhhh Aether Currents are pretty quick and a once per expansion thing, not some kind of long grind that would keep someone playing for long. You can generally easily pick them up as you're progressing through the msq and rarely need to go much out of your way for them, with a couple exceptions in the Lochs etc.
