It's clicking two buttons yes, and it's not a huge deal... but for some of us that's also a loading screen which can last a few seconds, and for me personally up to 10.
And if you have to get there often, then it gets somewhat frustrating.

However, a tip for the gatherers/crafters turning in collectibles: just teleport to Eulmore or Radz to turn it in, those collectible appraisers work with the new stuff too. It's literally only for combat gear upgrades that you have to be in S9.

Also a thought... it is kinda noticeable how ShB and EW both put you practically right next to the tome exchanges and collectible appraisers and such and all that for endgame stuff. Still had to walk a bit, but it was within sight.
Stormblood however, had quite a large walk from the aetheryte, or you did have to use the aethershards to get around Rhalgr's Reach. BUT, you could also use mounts to get around.
Heavensward had Idyllshire, also didn't put you right next to necessary shops. But you could also use mounts.


So since S9 has more in common with Idyllshire and RR, maybe just enable mounts so people don't have to get into another loading screen, which actually feels better for gameplay than another loading screen (even if it's the same time investment)
