Make the Lord a set character again, take inspiration from the likes of Chrom and Dimitri for characterization.
MU comes back but is explicitly a tactician for the army with no special blood or great destiny. Just a vehicle for the player to experience the story and receive exposition.
Reduce the number of romanceable characters to 5 women for male MUs and 5 men for FeMUs plus one bisexual character. In return, greatly expand upon the romance/support element, basically add an entire romance visual novel inside of your strategy game.
Let characters pass around skills via support chains, some support chains can unlock class changes for certain characters (but no class swapping otherwise). S supports are back but no children.
Kill Treehouse
Return to Fates pair up and class balance, giving single weapon classes extra invisible stats and S weapon rank was a cool idea even if the S rank weapons all sucked.
Give us a shit ton of units to play with again so iron manning doesn't feel so miserable. Stop hiding important content (like entire chapters) behind characters that can die.
You can have your evil cults or whatever, but the core of the story should return to "evil emperor starts invading other kingdoms" as its core.
Stop nostalgia baiting, nobody outside of Japan cares about Marth.
