Which got me thinking about adapting SotC to handle a higher-magic setting than the default one -- Evil Hat has the rights to the Dresden Files RPG, and there are fanmade magic systems. Which got me thinking about the fantasy worlds I favor, like Avatar or Slayers, where the non-magic cast are just as bad-ass as the magic cast. Some of it in Slayers is that Gourry carried a magic sword, but against 'normal' opponents, he didn't especially need it -- the magic mostly seems to counter creatures not harmed by physical weaponry. (TRY did a bad job of handling this, but Revolution showed this well. Even when Gourry is captured, and his normal sword is removed, it took him only one 'grab for sword he didn't have' to get into 'defend Lina though unarmed stuff' and only ran into problems when a deadly swordswoman and magic-using assassin showed up. For that matter, he was able to hold his own in a swordfight against a foe with superior armor with an improvised weapon Lina made for him out of stone.) And in Avatar, characters like Mai, Ty Lee, Sokka and Suki (or, for that matter, Pian Dao) are all shown to lend their own skills to fights and hold their own against normal opponents, even benders.)
It's not quite about power, unless you consider different types of power. Pretty much, the old Justice League debate. Characters like Superman has a lot of innate superpowers. Batman has a lot of resources and contacts, and is at the high end of human ability in both smarts and brawn -- all of it is 'mundane', just exceptional -- so he can use planning plus 'stuff' to hold his own in an organization of Supers. One doesn't feel like Batman is a token member of any group of Supers he's in, or exists only to fund the group -- he gets his chances to be awesome, even if he can't punch through safes or fly.
I guess it's a fondness for a world where magic is Cool, but there are many ways to be Cool. You can be an amazing swordsman, or a deadly knife-thrower, or a martial artist able to disable with a single blow.
(For that matter, one of the Dresden File RPG development blog posts points out that Murphy might be a normal mortal, but she's got her own resources and skills that make her just as important to the plot as, say, Michael (a holy knight) or Molly (an apprentice wizard) or Thomas (an incubus) or the Alphas (weres).)
