I would think that a good compromise would be to give them a static buff that isn't linked to there class so that you could give them a Stat buff and horse but keep them technically as the same class that can promote at any time.
This looks really cool (:
One question that I have though is whether or not saves from this patch can be continued once more of the translation comes out.
if anyone would be interested, I made an automatic class change randomizer for Shadow Dragon that gives you a txt file of your randomized classes here:
This is a program that will generate a text document with randomized class changes for all of the characters in Fire Emblem Shadow Dragon.
Fe 11 Randomizer.zip
instructions
1. Unzip the file
2. Open the dist folder
3. Run the ShadowDragonRandomizer.exe
4. Your randomized list will be Characters.txt in the same folder
