Issues with some zones and aethertes, please do not repeat this in SB

It's not a fault of the system that nodes spawn at SPECIFIC hours of the day, giving you the time PRIOR to that node spawning to make your way there.

I'd have welcomed an Aetheryte outside Idyllshire (that little goblin outpost perhaps?). Doing a scrip run I found it was just possible to get from the Adamanitite ore in Azys to the Morels in Dravanian Hinterlands, if you got the Adamantite as soon as it popped and went to Anyx as opposed to trying to go through Idyllshire. Even then it needed a bit of luck; I got sick of nodes slamming shut in my face just as I got to them in both Dravania and Sea of Clouds.

So, if the Devs are going to continue with only having timed-nodes up for 55 Eorzean minutes, placing Aetherytes to allow people to bypass areas where lots of players congregate would not be a bad idea, nor would spreading them more evenly across an area to enable access to timed nodes.
Personally, I'd prefer a return to the more relaxed gathering we had in ARR, with timed nodes up for 3 hours so you could actually run to them instead of being forced to teleport everywhere, but that's another discussion.
