I imagine virtually none of these changes come as too much of a shock to anyone. Allowing the full force of the wild card system to come into effect was an obvious result of an expanded championship. I'm sure this was always the end-game of the wild card system, it just would have generated too many bids if it didn't have all the proper qualifiers attached to it in the 2013/2014 season. It goes a long way to discontinue the idea teams can be underrepresented, and doesn't paint double or more blue banner winners out to be bad guys (not saying it should happen anyway, but it does).
The RAS changes are going to come with some apprehension but I feel there isn't a silent majority against the change. Until recently you could have made the case for RCA's to have the same kind of added criteria but I think in the last couple years the bar for that award has been substantially raised worldwide.
In my opinion, the new implementation of the waitlist is a long time coming anyway. There is a selection system for waitlisted teams at regionals that is more than first-come, first-serve, so why not for Championships? It's too important of an event to have it boil down to a fastest-finger competition; save it for the veterans trying to cram themselves into the Palmetto Regional
Big fan of all 3 moves.
