The amount of wipes you get on LFR N’Zoth. You are better off doing Normal. On top of that, better gear than LFR. Just watch Fatboss video if you don’t know the mechanics. There are raids for N’Zoth kills. I’ve seen some progression raids too.
Now I need to shrug off 5% wipe on M N’Zoth from my guild raid. Its becoming a torture after 245 wipes.
