i think they need to think about cap increases, people have been level 50 for months. Also getting battle figured out extends past this cap, it will always need to be adjusted, unless you plan on getting no new skills and essentially the same playstyle for your whole career. Adding cap quests will be a milestone, and content, its not a bad idea, doing it per class makes some sense, though it should then not be the same quest for every class, and should also be soloable, because if its not the same for every level 50, good luck trying to get help doing it if you arent in a LS.
