Has the LFD tool in WoW ruined the MMO genre?
I'm being cynically exaggerative here but honestly do you think it essentially goes against the core of the genre? When I look at LFD, LFR, I see the beginning of the end of MMO community and social dynamics. I also see the outcome of progressing the genre further in that direction to basically lead to the Destiny formula: Shared main city, and instances. Even the zones are technically instances, they don't link like a seamless world does.
