I think you overestimate how much Valor I would have had. An LFR doesn't give that much (is it 40 or 60?) when you consider even the cheapest thing is 1250. You really have to supplement it with dailies and dungeons, which Blizzard are keen to point out are optional.
I can't be bothered to do more than one faction's dailies in a day, if I bother at all. Right now I do Dominance Offensive, which is about 30 Valor, but the thing keeping me going there is the story. Who knows how that will be when it's over.
I've had enough Valor over time so far to purchase a 489 neck from Klaxxi and 489 shoulders from Golden Lotus. I crafted myself 476 chest and gloves and a 463 2H axe which I've upgraded to 471. Also got "lucky" with a Scenario that dropped 476 boots from the cache. And soon I will have enough Valor to buy another thing, maybe a ring from DO (493ish?).
But as you can see, I could really do with some upgrades on other things. A few drops, even ONE drop, from LFR would have been nice.
I'm sure I could "grind" the dailies more than I do, but once you have to apply that word to something, I lose interest.
