I liked Cage in the very beginning... but
Cage has been the same exact Cage since MKII, with no revamping, only unnecessary subtractions. Cage was personally my favorite character besides Rayden. But I've personally been tired of seeing him, since they killed him off (literally killed his character) in MK3. He was never the same, plus how can you take away such a signature move like his infamous groin punch. Cage without the nut punch is not Johnny Cage at all. It's like having peanut butter without jelly, kool-aid with no sugar, cake with no icing...
I'm not opposed to him returning. I'm opposed to him returning the same. If he does return, he should be almost unrecognizable (other than his signature moves); I'm talking Extreme Makeover: Special Edition. All of the characters need extreme makeoers, Johnny Cage especially.
