I generally disagree with you) Jebus Cross is already as imbalanced as can be) The strength of Conflux and Necropolis will only increase due to the chance of a native center, and thank God for that, it means they will be on equal footing with other towns. What secondary skills and Pandora's Boxes have to do with it, I didn't understand at all. However, you're the organizer, so it's your call what to play)

If you don't understand what secondary skills and Pandora's Boxes have to do with it, then you need to spend time understanding what they are and how they affect things. The center chance is already a chance, and that's already a disadvantage. We sometimes take restarts due to, for example, Valor lacking two stacks, but here — to play the main part of the game, reach the center, and discover an imbalanced situation — is very unfortunate.

By the way, what will be played is not only the organizer's call, because once a single template is announced for a tournament, it cannot be changed. 42 players registered for the tournament on that template, which is in the link, and that is what will be played.
