Is Superman above the top tier?
Really?
I mean, chances are hes beaten or stalemated your favorite character from DC, so long as its another hero.
His average from 99 to present has been pretty high, due to cockstroke, i mean Jeph Loeb writing.
He's been shown as probably the most competent hero in DC, next to Batman, Robin and the other Batbooks(Nightwing not included).
Do you think he's above the top tier?
Even if you don't feel its true, could you see how some might come to that conclusion?
All mainstream companies are game.
