The members already in the League are a few dozen, the whole roster including support staff is perhaps a few hundred at the start of the RP. The League is meant to keep the peace in a vast country of hundreds of [i] millions [/i] and eventually the whole world and beyond. Trust me, the PCs will get their fair share of the action and even more. Because in real missions crippling injuries and even death can happen and the most powerful might not always be there. And there's more to fighting villains than fighting them all-out in broad daylight. There are infiltration missions. Investigations. Things that require subtlety and sneaking around and not just smashing stuff. Besides almost everyone chose to play 'C-Listers" of their own volition, most of the PCs are small-time amateurs because they were created by their players that way. It's no action of mine that makes them that way. And everyone loves underdog stories anyway :P
