Why am I not getting any rep via LFR? (Done 2 sections so far this reset, no rep at all...)
That said, I missed most of the last two weeks of raiding on normal, and LFR gave me nothin'.
So I don't know. Maybe it's broken or maybe LFR only gives rep up to a certain point.
World bosses do give loot, RNG is RNG. As Tziva said, if you have done a boss on ANY difficulty that is it, you won't get rep from that boss in the others. If you do it on LFR, you won't get it on Normal/HC. If you do it on Normal, you won't get it on LFR/Heroic, etc.
If you are 100% sure you haven't done the bosses at all, check your Rep (to make sure you're not Exalted ) and then make a ticket.
And I already said I've only done LFR this week, and I've gotten no rep.
A gm is getting me my rep and is resetting the triggers on world bosses for me on my character now.
Two weeks ago I went on holiday and missed my normal raid, but I did run all four wings of LFR with zero rep gains (which I noticed only because I was a hair away from revered). Last week my normal raid extended instead of reclearing, and again I got no rep from LFR.
This week I ran normal so I finally got my damn revered belt.
