So I am not just talking about your favourite and least favourite characters, instead lets look at categories.So...

Best new fighter

Most improved fighter
least improved fighter
Best use of gear mechanics
Worse use of gear mechanics
best design
worst design
coolest shader
worst shader
Best premier skin
worst premier skin
etc.
eg.
Best use of gear mechanic- Green lantern, he seems to be the most obvious choice for use of gear mechanics, with both his shaders and designs.
Best premier skin- This is a hard one, but probably Power Girl. I would say Vixen but she does not use the plethora of her powers.
Best new design-Black Canary or Black Adam, personally I am not a fan of a lot of the designs or I think they are just ok.
