Over the last couple of days I've been getting more and more interested in making a FE ROMhack. There's a lot of information on how to do it so I'm sure that that's gonna work out somehow, but there's something I can't find information on: When creating a 'new' unit for your game, how do you decide the base stats and growth rates? I know, I know, you can basically do anything with them scale the enemies or something, but let's say I wanted to insert a new unit into FE8, where most of the time you're fighting generic enemies, and I wanted that unit to blend in with the rest, so it's not noticably stronger or weaker. Is there a set amount of points that I could distribute as base stats? Can I take an existing unit in the same class, add up their growth rates to a total, and divide that total on my new units growth rates and call it a balanced unit?
I'm really hurting my head thinking about it, so I thought, why reinvent the wheel when someone on this forum probably has some wisdom in this regard already? :)
