@SamJaz: Which one
@SekiryuuteiDxD: Because I disagree with the method. By saying that we already have an ice user turns people off the idea. If there was a list saying that there was already a seamstress, we never would have had Haruko. If we already said that we had eldritch abominations we might not have had huntsman. This checklist is the wrong way to do this.
I'm not an RPG player. I wouldn't be able to help you as much since I don't know the community well. Why don't you ask @Sonata @Vapovile @SamJaz @Lobos_Del_Rayo to walk you through the RPG community?
I couldn't find a forum thread where you can talk with folks.
