I've Lesser Reincarnated a number of times, and while I appreciate the idea of being able to revamp the appearance of my character, I hate having a random appearance for a start, instead of the one the character previously had.
I'm forced into taking screenshots and the like to try to keep him with the same eyes, nose, eyebrows... And for things like hair or skin color, it's almost impossible unless you wrote them down at character creation. I understand that custom hair style and color are gone, but why everything? It might be explainable for a Greater Reincarnation where you can even switch to another race, but certainly not for a lesser one.
Could it be possible to have the old character appearance in the character generation step as default when reincarnating, instead of a purely random one?
Just my 0.02 cents.
