Just a suggestion, but I think it will save a lot of grief and allow players to still work together as a region.
All remaining rounds are 4 region crw. Promote the top 2 from each round until the final round.
This will not disupt anything that yall already have, calendar wise, will be the same amount of events left.
If there is an issue as far as recurring match ups, can switch the facs up between the next 2 rounds, then final 4 wont matter as it will be 4 facs anyways.
