The main problem with endwalker is there are so many character but very limited time for everyone to shine, considering the usual age of most elezen, alphinaud is considered veeeeeery young even with all the experience he had, even having near other character in scion will make him the lesser lead, for him to actually have better character development is to actually being less with other scion and try to solve problem by himself, even with being with WOL or any other scion will block that character development because the wol and scion can solve the problem faster either with brute force or smarter way of solving it, i think the direction of the game for the scion to disband and kinda go their oen separate way is a good thing, especially with alphi and alise with the least interaction with wol or other scion, that way they can be more mature and learn to stand on their own, the sad thing would be we didnt see any of that as player
