It really does hurt the community. Though I'm not going to cry too much because our community is pretty worthless as it is.
Everytime I've ever used a content finder in an MMO I never ever have spoken with the other party members. Also the social aspect of forming the party is removed. It also pushes MMOs closer to a First person shooter feel where all you do is sign up for a fight, Fight, win/lose, next fight. I thought MMOs were more than that.
