Would it bother you? Yes or no and Why.
Some day's I'd say no it wouldn't. There are moments when I miss the way progression use to be. There are also days when I love it, more so than not. Why? Because my schedule is normally very hectic and changing and as I get older (have kids,work, sports with kids etc) a raiding schedule of any type is almost impossible.
How about you?
(I predict that as much as people dislike LFR more would want it to stay than go away)
