I have spent so... so much time running around LL Upper Decks... because there are only 3 aetheryte there, and most of the time you have to do the Aftcastle to get to anything that is there.

I think there should be an Aetheryte AT the BSM/ARM guilds, one AT the Maelstrom command, and one AT the adventurers guild. Ul'Dah has 5 aetheryte that are all equidistant equivalent to where I have to run from the aftcastle every time I need to go to the Upper Decks. It's exhausting. For my character anyway.. for me my finger is sore (emotionally) from holding down W all the time (and my metaphorical finger for pressing auto run all the time.)

Please... please put more aetheryte in Limsa. It would just make things so.. so much better...
