Only way everyone would be happy is to have cross server sage only activate for a particular server when insufficient numbers of players register for that day's sage. Sure it would add complexity to the coding, but I really cant see anyone not liking this, since those that already get sage dont get reduced odds of obtaining results, and those that wouldnt get a sage on the day get to participate with other servers.

(Although I could be wrong, regardless someone somewhere will find issue with any action lol).
