Hmmm... Most of the ideas that I have are simply improvements of what we currently have, like the Glam system, etc... but if I would add something completely new it would be a "Performance" version for Dancers.

Yes, we already have a ton of /dance emotes, but this would actually be a system of "live" dance, where you push certain buttons to create flow in between a set of movements. We could have, instead of bard instruments, dance styles, like ballet, or tap dancing, or flamenco... obviously with custom names, since most are drawn from real world cultures.
