Well what would someone who plays LoL need a Kotaku for?
LoL has it's own news video thing with a girl no less. Its in the in-game browser/client and she drops most of the news.
The other stuff people may be interested in is covered by streaming websites and whatnot and people use community forums to talk about changes, new characters, ect.
It really is a "game" in the truest sense and it's better served by things dedicated just to it. I'm not sure LoL players are interested in Opinion articles about thier "sport activity". Plus, what's Kotaku going to write about? How bad the female characters are? I doubt LoL players want or care about that subject. At this point what you can talk about is tournaments, new characters, and other things the community already talks about with each other.
At this point I like to read game websites less for reviews and more for personal opinions or actual stories. I don't think LoL is the game to fill those types of articles and it dosen't need to be. Though I guess we may approach a time when the stories are about players behind the game, I mean Real Sports did in fact have a piece about e-sports with interviews with people from riot games, but we aren't there just yet,
