Ooh ... That's a great thought. I'm not exactly sure what you meant but you have my creative juices flowing.
What if fellowships are assigned a certain league ... they compete in their league for top prize but they also compete in the overall FA as well. In other words, a fellowship might place 1st in their league with like-ranked fellowships (with appropriate prizes) as well as 6th overall, with the regular 6th place prize. So they can win double prizes and also feel good that they can get a first place win even if they aren't insanely high in their world. Fellowships can be assigned to a Pearl league, Diamond league, Ruby league, etc. They will be competing only against fellowships that are pretty much their level as far as ranking goes. (A fellowship that has a 1 million overall score does not have to compete against a fellowship that has a 20 mill overall score.)
Or, what about fellowships that choose their league? They cannot choose a league below their level ... since it wouldn't be fair if they dominated a baby league. But they could choose one above their weight if they really want to. You'd have a lot of 1st place winners that way among fellowships that could not possibly hope to get a first place win the way it is now.
Or what about fellowships that can invite other fellowships to join with them in a particular league?
Hmm ... what about fellowships joining together for leagues for other things too? Events? Member partnerships for when members want to take a break or do more?
Anyway, I may be totally off base with what you thought, but you've inspired me!
