I was thinking in my mind maybe I'd combine CAS with BB, so they only make 1/3 of the composite score instead of half? Something along those lines.
Here's what I would rank for the two categories I actually can off of the top of my head. I'll have to spend some time filtering BB and CAS by pack to refresh my feelings for those. I also gave seasons a boost of 50% on it's Gameplay score, because it has NO world largely because the Gameplay is the primary focus for the EP and having it has an effect on every single World you have access to. I feel it shouldn't get penalized for that.

This puts them ranked in this order (so far) for me...which is pretty close to what my gut would have told me....which probably just reinforces that I don't see CAS/BB as being as important for a EP. Of course, I also use a lot of CC. I'd surely feel different if I did not.

I posted this here without the CAS and BB rankings because, honestly, I'm curious how it will differ once I go through and figure those out.
