Interesting points on difficulties. For the record I believe raiding is different for everyone. One man's normal is another man's mythic, and neither is better or worse than the other solely because of it. I love multiple difficulties for a lot of reasons, but 50% of the reason I loathe them is the pedestal some people feel it places them on when looking down at others. (The other 50% is the gear level explosion, but that's a different topic.)
Like I said a ways back I wouldn't open LFR in full on day 1. If they want to gate it a week at a time, sure. But two weeks between wings is just brutal. Between the time spent waiting and the inevitable shit "elite" players will be spewing once LFR opens up in full and they "have" to go through it for gear, I'm thinking about just pugging a normal every week and calling it good if I can't get a group.
