This is something that won't leave because you take it for granted, in other words, it's just a game. It's not a girl or something, rofl..
Also, Blizzard is happy with how they have LFD set up, they're not going to just remove it for absolutely no reason. If you want to argue that then go ahead but I won't waste anymore time than I already have on arguing stupid things with people who hate to be wrong.
