we have a split community already (1.23/1.24) so then we'll have four communities

I'd suggest making a three-month poll to see how many people are interested in playing this ladder system, how many are interested in watching others playing and how many are not interested at all and will just ignore the system. And maybe another poll too just to see how long people think it will be alive.

Check for people who will use your product first, else it will fail for sure.
