Of course, when everyone else and his or her specially trained dog or cat are doing the exact same thing, it's hard to feel like a unique snowflake in the hero crowd. While NPCs are supposedly helpless and need a dashing, daring stud or studette to champion their cause, after a while it may seem like they're more "lazy bums" than "weak innocents."
Or maybe I'm wrong. Maybe there's something in MMOs that does, in fact, make you feel like a hero. Maybe it's not anything scripted by the developers, but instead happens out of the blue. Perhaps you're the healer who kept your raid alive, or the person who gave up a night to help out a lowbie in the guild. Maybe you saved a total stranger from annihilation, or you chained sixteen crits in a row until the bad guys were weeping for mercy.
