Quite easy, the end game design for raids currently is them clearly planning to have a massive outdoors raid boss encounter using a zone.
Be it a Titan, Galakrond, iridikron forma da continento or what ever.
All the tech is already there, they've been reusing outdoor zones for raids and dungeons, they clearly enjoy using skyriding in raid encounters. All they need to do is make a massive raid boss you actively need to fly up and climb across.
