Awesome! I cannot wait to see it integrated with Ultimate Points, Sajaki!
I also wonder if you might consider making a version of this that is customizable for games we write ourselves?
I have tried to customize using an existing game structure that comes with bbDKP, but it is not quite right. (Classes etc.)
Right now, I am planning on using Ultimate Points and Easy Shop along with manual ranks. I am waiting on Malk's dicemod to be stable and will be installing that as well.
Being able to use your system for the RaidPlanner, portal and rankings alone would be so awesome.
I have not played WoW or any of the games you support (thus am not completely understanding how it all works), but I think what you have created will easily lend itself to the type of games my community does play.
If you want to see what I am working on to give you an idea of what I am talking about, send me a PM and I will give you a login at my new site.
EDIT to add: I think you already had this idea for an RPG mod over at your forum
