This is by far my favorite randomizer to date. Just a couple pointless suggestions I want to make:
First, add a palette to Eirika and Ephraim. As it is, when they're randomized, they just end up with the default non-paletted version of their classes, which IMO is quite boring, especially when we have neon-green priests healing around.
Second, add branching promotion to soldiers. They could promote into paladin or wyvern lord, making them not be completely useless as an unit. Having them promote to trainee 3 is quite boring, to be honest. :/
Thank you for your hard work <3
