The main problem is that the world buffs are too powerful when all of them are used together. Full world buffs allow guilds to disregard boss mechanics. Not completely obviously, but to a great extent. If you can kill Gluth before the first decimate, if you can kill Faerlina without needing to sacrifice adds, if you can kill Maexxna without getting stunned during the berserk... we can go on and on. Is this what the community wants?
I think world buffs should be available in all raids except for naxxramas. Reason being that theres nothing else after Naxxramas. World buffs can help new guilds establish themselves on the server, build up gear in the lower raids in order to get "ready for naxx" and the older guilds can enjoy faster clears on their farm raids and look forward to the "real" challenge on their naxx days.

Ton of people will probably lose world buffs on trash before bosses, anyway.

- also Heigan got 1,800,000 HP, and first dance is after 90sec, thats 20k raid dps to kill him before dance
- Ouro 2,000,000HP is speed killed within 62-80sec already

Curse vs Patchwerk

- no wbuffs
So only 1 video with wbuffs used(Ony + Rend), no Zandalar or DMnorth buffs. No excessive wbuff stacking.
Im not saying this is proof nobody used wbuffs, kek.
I post this to show that stuff is killable without wbuffs just fine, its not the end of the world if you disable them just for Naxx.
So +1 from me, disable for Naxx because its the last raid we get.
And please do it in a nice way, like KT yelling something: "Your Warchiefs Blessing does not work in my Realm of Death!" and purge...
