You mean 60 people, but starting War with teams of 6 (no support member) is the most likely option, assuming we get the 60 people instead of 72.
We're now at 62 applications, so unless we get another 10 we will be playing without support team members. It's unfortunate that
that's the position we're losing, as it's not a serious problem to have any upgrade-and-rare-poor players on your team. This also means (I assume) section 7 of the rules will be completely axed, relics will be axed, teammates will not switch to support teams later in War, and upgrades won't increase throughout War. I'm hopeful the WMs will consider putting a different role on the chopping block.
If team sizes are modded down before bidding starts due to fewer applicants, how will number of blind bids, number of total bids, number of cards in vault, etc. be changed?
