-Say'ri not having more supports, and a child of her own
-A lack of inspired maps
-Lack of chapter objective variety
-Not enough map variety in the 1st series DLC maps. A part of me hoped that in each of the Legacy missions, you would play each on a different map, tied to the game of the character you could recruit there. (ex. In CoY2, you play on an FE6 map, CoY3 an FE10 map, etc.)
-A minor thing I miss and wanted is that that characters names don't become green-highlighted on the Support Log page after you've gotten all of their support conversations.
