I find that the current raidmodel. Where you "have to" run lfr for upgrades. And you have to do daylies for charms. Is worse than the wrath model concerning burnout.
Sure at some point you reach a gear point where lfr isn't necessary anymore. And if you grind daylies like a mad man you end up with enough charms for several weeks.
But the same could be said of the wrath model where at some point you wouldn't get any upgrades anymore from doing 10 mans.
And when I compare the time invested in doing/waiting for an LFR to open + the time wasted on doing daylies for charms. With the time I used to do 10 mans. I would have to say that back then I used less time and I had a lot more fun because unlike LFR/daylies i was using my time in a more of a social setting with funny interresting people.
And I will say it again LFR is from a social multiplayer perspective complete rubbish. I go in after waiting 30 mins, with a bunch of strangers that i will never ever see again and steamroll through content, and after that I teleport back into the world and que for a new LFR, with a bunch of strangers that I do not care about.
