I honestly agree with them all. Sure Blaze is well known, but is she ABSOLUTELY necessary for the 4th movie? I mean, Amy's introduction and Metal Sonic's should be the last for the movies, as there are a bit too many main characters now. Maybe 4 or 5 MAX. Have as many villains as they want, but the main characters have a limit. So people new to Sonic wouldn't really take Blaze seriously until she joined Team Sonic. That brings me back to the problem, there is enough main characters. Maybe she could just be a side character or have subtle hints that she is somewhere in the universe. Anyways, there are too many characters for Blaze. The only reason I didn't mention the others is because I love Sonic and I didn't even know half of those guys existed.
