I think we've used a reasonable amount of seats given the extent of our membership(s) over the years, but I don't disagree with you.
That said, this is only for prioritization. Someone still has to pony up for the actual seats and bear the cost, which ultimately is what gets fans in the door.
But I wouldn't be devastated at all if they cut the number of seats you can buy under one membership. I WOULD like the option to bundle memberships together if so inclined. Maybe that exists, but we've never needed it, and I haven't looked.
