All the Firestorms is too much like having multiple Green Lanterns all on Earth.
Between a couple of GL and FS crime should be quaking in it's boots.
The gimmick I recall on Firestorm that was so interesting was that he could do damn near anything if he only knew how to harness and access his powers. But he's a teenager, he'd rather look cool. With so many FS characters running around you'd think a few would be focused on fine tooling the power of that matrix. I stopped reading at issue #2 so maybe they did.
