phasing, or layered quests as some call it, are old news, but imba nonetheless

maybe link to the specific place where its mentioned, instead of just an empty side

nub

Just didnt know it was called phasing

It's basically quests that change the world for you. Say you did a quest to rescue the king of stormwind, and when you completed it, he'd be standing in stormwind for you, but not for everyone else who's not completed the quest.
The starting DK quests are a great example also, where the scarlet crusade has a town near Ebon Hold, with farms and peasants everywhere, but further in the questline, this town is under attack, and in ruins, this is what you see, while others who's on previous stages, will be in another "instance", and see the town as whole.

In AoC they solved some of those things by putting NPCs into buildings you had access to only if you had the quest. An NPC could then actually die at the end. Because you no longer had access to the building he would be dead to you.

We have seen the same at least one time in Wow as well. An NPC is trapped inside a toilet in Searing Gorge. Only problem is that his calls for help can be heard after you rescued him. :p

Phasing sounds like a lot more advanced and better. Looking forward to seeing it in action.
