Anywho - Luke Cage started out as like a ten tonner, and he's thirty now (if I recall correctly.)
Ben Grimm started out as a five tonner, and he's like ninety now.
Anyone complaining about them? Wishing they'd go back to the good old days?
Nah.
Characters get stronger, faster, smarter, better. They get upgraded. They get more and more impressive feats, constantly trying to 'one up' whatever came before. Constantly trying to get fans to go "Holy shit! Awesome!"
It happens. Quit ya bitching.
