I doubt this is still being worked on, but if it's fine with you I'd like to suggest maybe making monsters a seperate box for FE8? One of my biggest issues is that my teams get flooded with the monster classes :/ But I still want dancers, soldiers, manaketes and trainees in the pool.
For what it is now though, I really like this. Good work! Im sure it took a long time to make, so good on you! :)
