Like the title says,I'm sorry but not being able to do the two Artifact Quests in LFR is bullshit.
The two quests I am talking about is In Nightmares and Essence of Power. These quests from what I been reading can not be completed in LFR.
I tweeted blizzard to confirm and will post the reply when and if I get it.
If that is the case then that is total bullshit. They are making NM+ raiding a requirement for people to progress there Artifact Quest Chain.
Edit: Also no where does it state on the quests you need to do NM+ to finish them.
