Very sorry for late replies everyone.
I've got an idea. How bout each stone have its own guardian who can use the powers in their stones alone. And when the guardians use their powers together, it'll be much like how Zorum can use the stones by himself. The thing is, nobody knows that that's possible and this is a discovered thing. And some guardians don't even know they are guardians. What nobody knows is God made each stone have a guardian so in case something wrong happens, when the time is right their responsibilities as guardians will reveal itself? What do you think?
