@panblanco. That’s a fantastic idea!
We can have a longer sign-up period and afterwards the initial ladder will be set up according to each participant’s latest rank. Unrated players will join at the bottom of the ladder. After round 1, the ladder will “live” on its own regardless of the latest ratings. This should make for some very intense games that are very close as players will more likely play other players of similar strength to theirs.
If we keep it at one round a month, it will be much more relaxed time-wise than the tournaments (which can still go on) - more people may sign up - and the king of the hill can keep their title for at least a month. Plus, players only have to commit to one game at a time. We may even consider to set the games up with lower star counts (32 instead of 64 per player) to make it relatively certain that they can conclude within a month.
The only thing I’m not too sure about is just keeping drop-outs in the system, it may take a while if high-ups drop out until they are flushed out of the system. For one game, okay, but then the ladder should move up accordingly if they don’t come back for the second month in a row (keeping in mind that unplayed matches won’t count for the ratings).
