I played mmo's while i was in college and university. It sucked up so much of my time. I would say that it's the reason why my grades weren't the best but I would have probably wasted as much time with something else.
LFD isn't an MMO. Not enough people play simultaneously on the same server to warrant it a Mass multilayer online game.

I was a member for a while. It made pretty much no difference, except you had access to a bunch of needless skills, and a house that is impossibly difficult to design
