I've recently started tweaking the GBA Fire emblem randomizer (https://github.com/lushen124/Universal-GBA-FE-Randomizer-Windows/releases/tag/v1.1.0) to try and fix some of the common issues that occur for me such as:
Heavily lopsided growths
Weird weapons (poison weapons etc)
etc
Wanted to know if there was any interest in these changes and if so, I can make them public. Also if anyone has any ideas, I can try and fix those too!
