To add my own advice:
-In campaign add personality to siblings, they dont react to/dont talk about your actions, if the cutscene didnt tell me that i was fighting them, i wouldnt have known.
-Extend the story in the campaign its way too short.
-Make the map phase more interesting.
-Make battle phase more interesting, and not so micromanagey, also less blobby. For example make built defenses count for something, as in buff their defense for one. Also for dragon transform there are 2 outcomes either its too easy to kill with it, or later, its too hard to kill with it especially once the ai starts to develop tech during battle, if the battle drags on too long, this needs to be better balanced. Right now the combat focuses on constant attack, which isnt a good thing for players who like playing defensively.
-Reduce price of game, i have seen deeper games with more content for 24 eur or less than this game has for 40 eur.
Or you can just add more content, so it's worth that 40 eur.
