I dont get why so many people hate mmo-s***

I personally dont use it, but i dont hate it
there are thousand of kids on this site and they have news with wrong informations and so on. Its a hp to confuse people who know more about mmorpgs than m-m-p-site do and this is rlly annoying. There are more reasons but i dont wanna start a m-m-o-site thread xD
