I fully agree with you. MMOs are about interacting with other players. Unfrotunately, for some strange reason people prefer to solo farm everything and need other players only to buy stuff from, which is quite sad.
So called "modern MMOs" seem to promote such behaviour by providing them with tools such as LFG which in reality result in player alienation.
"Hey ! I don't need, I can find randoms to do stuff with via some cross-server tool"
