The UI seems like it's going to be way more interactive than in 2.0, so with elements such as drag and drop, I would think it wouldn't be too hard to click on an aetheryte in your map to teleport to it. It may not make it in for launch since they're already behind, but maybe it's something that can come in after. At this point, they really can't add more new features else the game will take even longer to come out.
