This can go one of two ways, and now there's a new issue.
I like 10 better over 8 because it gives more variety, although 8 can filter down to the top members.
Issue: You said that clan members not representatives COULD battle. Will they have their own seperate little area of battle? It could be problematic if mixed with the actual tourney because let's say I face one of your non-reps, and I win. Is that still a point for me?
It would cause an imbalance in my opinion.
@chibay: Awesome; I'm just dying to see what the Metagross itself looks like ^^
@Loto: I talk to Venomancer and Andy daily off PC. There's you, Chibay, noticed Abdul on too, Hammerhead, Deanodance, you, Bass, Dunlop and a couple others I'm sure if I missed them by accident; I still need note from Knight of Arceus though.
