They don't, really. The set bonuses are there in normal and heroic as well, and the item level is even higher."
They know how to look dumb, so they throw that kind of stupid answer...
Set bonuses do give a advantage. The LFR ilvl is high enough that good set bonuses from new tiers are real improvements over keeping your old set bonuses with a little higher ilvl from (maybe) last tier heroic sets.
So, to finish your set (2) and set (4) faster and get that damn good boost, every raider will feel the obligation to run LFR every week to get the damn set pieces (not mentioning trinkets with godly procs that always shows up every xpac and their ilvl doesn't matter since is just a little higher or lower).
When you take in consideration that LFR benefits a lot 10man raiding (few drops per boss in 10man, more decisions of who will get their set bonuses 1st, etc, while new LFR loot rules are damn good for all 25 players), it's a must have if you want to progress faster (and without most of the "who gets the set bonus" dilema).
