As long as i get to be the frog
I think the difference in opinion here is that the "character creations I've laid down" are literally just "talk to me about your concept before you get invested." I don't give too many guidelines because I want them to refine their concept narratively first, and then we can start working on how best to represent it mechanically. This is important to me because I'm very liberal with homebrewing.
See my expectation is that if you really want to play something not in my allow list to talk to me about it and let's see what I can do to accommodate.
