I don't know if I want to risk my mental health for a boss like Gelbin in LFR... but then there is the mount (and the fogbreaker from Jaina, and my Mage main is still missing the off hand and I would like to see something when that whiny coward phases into Phase 2)
If you mean specific items/appearances, OK. If you mean ilvl, of course you can do better by killing Ivus in Darkshore or running the Darkshore weekly quest when each event is available. Admittedly, you can only do one of this once a week, but the odds are considerably better. Blizz's decision in Legion to make LFR useless for gear leveling has meant each LFR wing is worth running at most once. Seriously, why would I repeatedly run LFRs for a chance at 385 gear when I can do as well from at least one emissary quest each week (guaranteed drop)?I hate to say it, but the WoD valor system at least rewarded improving skills as a route to, or at least byproduct of, getting better gear.
