Yeah N’zoth Lfr is arguably harder cus in heroic at least you know the whole group is trying! In Lfr a lot of the time people come in not knowing wth they are doing and just want to be carried now that usually works most of time but N’zoth is not a carryable fight and with too many lazy people who just think they can just dps lazily like other bosses the job doesn’t get done and they wipe the whole raid. Then they quit when you wipe after the 2nd or 3rd attempt and you get new people who are likely the same way and it just goes on and on! I even asked a group one time if anyone from the original group was still there a few people said no they all left and they were on attempt 14.
