Personally, I hope they keep the rest of the competitions the same. Just do D1 and D2 at Worlds. The small gyms are already getting bids, so they don't need special bids allotted for them. So I think the people who should be at Worlds will get there, and that's where they could split the divisions. Just at Worlds and not in the rest of the process (bid comps, etc). I hope that they don't split into D1 and D2 at all comps, and I really hope they don't designate X number of paids to D2 and X number to D1.... If you earn a paid you earn a paid, and you shouldn't be given one just because they HAD to give one to a D2/D1 team and you happened to be there.
I think that if a D2 gets a paid bid, they should have the opportunity to move up (only if they choose to though). We shouldn't restrict the teams who are small and can compete with the big gyms, but we shouldn't let anyone choose to go D1 just because.
