Honestly, we can we just remove N’Zoth from LFR, please? Seriously, it’s not even worth being there. Just remove N’Zoth, play the cutscene, and give everybody present a bonus roll opportunity from a boss they never fought.
The gear from N’Zoth LFR is not useful or particularly powerful, and people can’t do the fight. So screw it. Remove the fight, remove the loot, let 'em roll a bonus roll if they really wanna waste it on LFR gear.
