RNG is still a factor, skill is still a factor (as you still have solo tasks you must achieve), and time and effort is definitely a factor since you have to be dedicated to raid regularly for a very extended amount of time.
As far as rarity, yeah, this one might be more common (although maybe; I don't honestly know how many casual people are that invested in the chain -- we could all just be inflating the amount), but it still has every other factor working for it. And rarity, even if you think its the most important factor, is still not the only factor, otherwise they've be downgrading the old legendaries that everyone has (like TF) to epic.
And frankly I think it would be real dickish on Blizzard's part to let LFR raiders complete the chain all the way to the end and then say LOL NEVERMIND! when it comes to the final reward.
