Skills still saved clientside - not server side
Update:
I guess this is wrong. In the time I wrote my short original post it had to download the position of the skills. It's just a slow process. Skills are saved serverside now, hurray. Now if only macros were.
It's interesting to note, though, how slow it is. I switched classes multiple times between archer, conjurer, alchemist, carpenter, thaumaturge, and botanist - and wrote the macros for each one, and tested the macros at least twice.
I didn't write this post until after I had completed all of that and switched to archer for maybe a third time.
After testing my other classes, it switched over faster, so maybe it just does it in one big chunk.
