It's not even ultimately about playing one against another. It's about the distinction between "Very loyal realm" and "Multi-accounts." Doesn't bother me if I can't play someone against someone else because they're just very loyal. It does bother me when the reason I can't do it is because I'm dealing with multis or clans. No, GMs are not the same, but the frustrations are similar in their nature.
But—and I believe I've mentioned this before—if Tom wanted you to be able to make
any headway by playing the Zuma against each other, you would already be able to do it. Adding more GMs will not change the cohesiveness of the Zuma as a group. The cohesiveness of their movement times and response times, sure. But not the cohesiveness of the bonds between them.
If there is not meant to be a way to play one Zuma against another, they simply will not let you. No matter how many or how few they are.
Do you just not believe me in this, or are you truly not grasping the concept?
