Personally I would like more variation in table setup. Is there any realistic way the following might happen?
- allowing Viewing yaku but only score them if you also form another yaku (so you cannot end a month with two cards on their own)
- making "dealer privilege" optional (if disabled, nobody gets points in case of a tie or if both players are dealt lucky hands)
- limiting the amount of possible (soft) Koi-Koi calls per hand (either always to 1 or only to 1 if the starting multiplier was higher than 1) – you may continue but the multiplier won't increase after the limit
