If you are serious about progression, you will do anything and everything to gain an edge, and you don't normally complain about having more things to do that helps get you that edge. The annoying thing to me about the argument is why LFR in particular is the one "mandatory" activity they don't want on their weekly to-do list. For the most part, it is quick and painless. I see it as being similar to the old "weekly" from LK, only it takes a bit longer. As far as valor earned per minute of effort, it feels on par with everything else.
If I were going to complain, it would be that there is no "rep-free" valor vendor. If anything feels forced it would be that aspect of dailies, but thats only temporary until valor "upgrading" kicks in.
