It's basically like bringing a gun to a knife fight; sure you'll win pretty easily but , who's going to respect you when you win , and worse , who won't laugh at you when you lose?
Found on the comments of a Sirlin article. This is basically my main objection to League. Bringing guns to knife fights happens all the time and it's a contest of who can do it more/better over the course of the game. Sure, it's balanced, but that doesn't make it suck any less for the guy on the receiving end of the pounding.
