Well we have a lot of newer creative members that are coming up with outside of the box ideas that are being constantly implemented, tested in practice and refined. Even you made us rethink how we show admiralty ranks and we talk about that as we speak.
There's a lot of things we didn't think of when this was written, and as the groups get fleshed I suppose we should try to keep it updated - a lot of the sub-groups (you can see none of the prefixes aren't explained in there even) are still
1) A work in progress - and we'd need to keep updating the writeup before they are finalised and constantly change it
2) I know even some amazingly thought out faction information threads can actually get confusing to newcomers when you have a bunch of sub divisions and groups listed and explained - so the question is if we even want to do that
At some point we will simplify the thing and update it. There probably isn't too much rush at the moment
