Things are very simple: tournament staff just personally don’t like some of our members and don’t want to give us spot. Problem is not in rules. Also why are you ignoring fact that you’ll ruin div B by placing us there?
This sort of silliness really is not helping your case.
As a newly formed team the possible spot in Div B is already a huge benefit over the strictly 'fair' starting out in the lowest div (which we try to avoid for reasons of more enjoyable play for everyone).
The arguments that it is not fair to put such a 'super' team in Div B is already bizarre, especially as you also argue that it means a team from div B loses a chance to promote. Who do you think they would play against if they did promote?
Any team that wants to be in div A, should be prepared to play in B and teams in B should aspire to play against div A teams.
The admins have considered possible options but removing a team that has won their place in A is a non starter and changing the whole tournament to accommodate one team has to be balanced against negative effects for other people involved.
