I guess I've always kinda been a victim of it, but then again, it's hard to not call your protagonist "special." If they were just some Joe on the street, then there's no reason for me to sympathize with them than any other mook or background character. There needs to be a reason to make them worthwhile enough to follow, which means making them "special." Take, for example, Kyon from Haruhi Suzumiya. He's the only ordinary guy, very average, his most notable feature is being boring, but he's still special in the story, in that he's the one Haruhi drags around.
Looking at my stories, I could say I'm a "victim" of special protagonists, but I won't, because I don't see enough of a reason to inherently think being special is bad. Ricky is an alien in human form, but he grows up as an ordinary kid who just barely begins to realize he's weird when he's 15, mistaking himself to be psychic. And this is after an ordinary human reveals weird powers.
Scoty, from a different book, has the power to make shields sprout from his body, but before then, he was just a slave. He also has "Passion," which isn't really "special" since it's technically an ability you could say we have in real life, but he's able to really accentuate it, much like a few other abilities.
I guess my standard would be, is the special protagonist exceptionally more special than anything else in the series? Ricky is an alien with powers, but there are other characters and people with powers that technically outrank him. Scoty has his various skills, but both of them are traits other people in the world have, so he's not alone. If your character is more special than a vast majority of others, you probably have a problem, but if he/she is also less special than your average character, you're not in the clear.
I'm pretty sure the concept of Law having limits was a translation error. -Wanderlustwarrior
