Scholar didn't get many changes in the Endwalker. It got some few additions to the class, but other then that its lot of the same as it was in Shadowbringers. My understanding/interpretation of the Scholar Class fantasy is "as a Scholar you study endlessly to find the best suitable action to take in any situation to prevent harm to yourself and your allies while having the powers of a corporeal fey at you will". Having said that I have a few topic's, changes and ideas I like to present
First ability I would like to integrate into other abilities seeing as most Scholars find it hard to use is "Dissipation". its clunky to use because 50-60% of your tool kit is linked to your fey. so i would like to split up into "Summon Seraph" & "Aetherflow"
First you add increases healing magic potency by 20% to Summon Seraph.
Second, you make "Aetherflow" usable outside of combat (as it was in Stormblood).
This makes "Summon Seraph" a more useful ability than it is now and it has a bigger impact on healing checks in boss fights as for "Aeatherflow" it makes it a lot easier to prep for a fight and you can always have it on cooldown so you can press it every 60 seconds.
Second ability I want to change is "Aetherpact" nothing too big, but I think it would be nice to have a little buff with 5% more damage reduction of the target when it is active to really make use of the ability when pulling larger packs in dungeons or tank is taking repeatable damage. (name of the buff could be "Fey Protection")
Third is "Chain Stratagem" stacking with other Scholars "Chain Stratagem". It has come to a point were Scholars that are in the same group are walking on eggshells around eachothers its the worst feeling in the world to overwrite a Chain Stratagem to a fellow scholar know full well that you have taken away 15s of Increases rate at which target takes critical hits by 10%.
And the forth is just an idea I would love to see added to ffxiv the customisation of your fey. Seeing as Selene and Eos have the same abilities and are basically just two different colored fey (since Shadowbringers) I would like to have an option of choosing both the color and the hairstyle of the fey I summon. Seeing as no one in the story or in the game ever mentions your fey/fairy (except in the scholar quest line when you get them). I would like to make it match the scholar that I am. Every scholar obtains different information and knowledge so it would fit my class fantasy perfectly.
