I think it's well documented you dislike LFR. You know what though? I can destroy most LFR arguments with just a few words. I find it fun. I actually do. Then I go on to raid normals and find those even more fun. I suppose it helps that I'm a social butterfly and don't look down on everyone around me and actually talk to people though. You'd be surprised how much nicer things get when you chat to people. Not everyone is going to just call you a douche.
And I am a casual player btw...
As for doing the quests, I probably won't in reality. My sub runs out in a couple of days and I'm taking a break until 5.4. I've not stopped playing WoW since my first break in TBC. Time for a rest for a little while
Truth is, people would bitch and moan no matter what it was or how you got it.
