Not weird. In first post on this topic, i said my own preference are street level heroes. Hell, my favorite "hero" was and still is Punisher (and i like to play that type of characters). So power levels around peak human to low level superhuman (fe WW2 era Cap in First avenger as upper limit power wise). Guys and gals that can still be taken out by more capable regular Joe human criminals. I only implied that, at least in my personal experience, in games, teams of heroes with vastly different power levels just don't mesh well, specially in more action oriented games. And from GM perspective, for that kind of team, it's hard finding suitable challenge where everyone can contribute in a fight. Throw regular human criminals, big guns walk over them. Throw superpowered mooks that can challenge big guns, they stomp low level heroes.
