Instead, there were around three hours worth of quests to complete, taking you from your faction's primary city, to the Chamber of Heart, Blackwing Descent, and more. When I booted up WoW post-patch, I expected that there would be a rather short preamble before I was stuck with the more repeatable content.

This is the loop of the patch: complete dailies and Visions to make it easier to push further into the Horrific Visions, and ultimately into the new raid: Ny’alotha, the Waking City. It's about getting the most done in the time allotted to you, with rewards allowing you to improve and stay within the Visions much longer. This meter bleeds over time, or drops when you take certain attacks from enemies, making it a timer predicated on your gear and overall skill. Entering a Vision, or the larger Horrific Visions, causes a Sanity meter to appear onscreen. This factors into the Visions, which are instanced encounters showing a world tainted by N'Zoth. Overall, managing and surviving the effect of the Old God's creeping influence is the general theme of Visions of N'Zoth. You can mitigate the Corruption with items like the legendary cloak or a new set of Essences You can also cleanse the gear at the cost of removing the beneficial effect. At low levels of Corruption, the risks are mostly annoyances, like a brief decrease in movement speed but at higher levels the drawbacks begin to stack up, like N'Zoth's minions spawning out of nowhere to attack you.
