What friends? WoW used to be the game where you made friends. My guild, for example, had real life meetings and we all met through WoW. Today they're all gone from the game, and the chances of making friends through WoW are pretty close to zero.

I quit in Cata, but got MoP recently to try it out. I did all those bosses in a couple of nights. It's was a complete waste of my time and money, and Blizzard's development effort. I would even take a handful of TBC style heroics over all those bosses, that's how poor the experience was. I won't be getting WoD.
