Characters should always be with their designated teams. Don't experiment with combinations. Don't make new character dynamics.
Silver should always be with Blaze. Blaze should rarely be around Sonic. Sonic, Knuckles, Tails, and Amy should always be around each other all the time. Shadow, Rouge, and Omega should never talk to anybody else. Teams are good.
Anything that makes Silvaze appear canon is good. Anything that remotely suggests a possibility other than Silvaze is bad.
