Not exactly, Horde has basically no risk in entering war mode, because they've got the numbers, so they do benefit from their basic war mode bonus without any offset. Most of these people do not want to pvp, they are just turning it on for resource bonus, for pve reasons. Meanwhile, people on Alliance characters are turning it off, because you usually barely see any of them. And this continues, without any solution in sight (other than dividing players into equal groups, rather than factions), so at one point one faction won't see any enemies to kill, it will only get harder to do any world pvp content that requires player participation.
Ny'alotha opened today and we have two cinematics. The first one plays just before the penultimate boss and we see Wrathion and N'Zoth. The second one involves your character and the Kamehameha-esque destruction of N'Zoth.
Wrathion & N'Zoth Cinematic
After the fight against Xanesh, Azshara reveals her plans and tells us how she wanted to stab N'Zoth with Xal'atath, Blade of the Black Empire, but ultimately, she gives the blade to us and Wrathion uses it to stab the God of the Deep and summon Carapace of N'Zoth.
Raid Finale Cutscene
Battle for Azeroth ends with a short cutscene and a 28 second-long cinematic where your character destroys N'Zoth thanks to the help of Heart of Azeroth.
What do you mean finally? Each warfront that's given superior gear at the same time as a raid releases has gone to the Alliance day one. This was particularly bad in the first tier of this expansion.
That they don't get it right away here is a first.
