Blizzard on 7.0 vs Blizzard 7.2

7.0 interview : Q: Do World Quests scale with item level, or will they just become trivially easier for greater rewards?

A: Once you're max level, the world isn't scaling with your gear. There would be problems if we tried to do that - what do you do with a fresh 110 and a raid-geared 110 fighting the same mob in the same place? We could some kind of scaling I guess, like leveling, to normalize it? But I think that would go too far in undermining the core sense of power progression that is part of an MMO. The stuff that was challenging for you in Suramar, that was challenging when you first hit 110 in greens...when you come back in Mythic dungeon gear, you should crush them a bit. The intent is that the content is is something you outgear, outpower eventually.

7.2 Mobs now scale with itemlevel ( probably to ensure you need even more play time to do quests)

Hope people will finally wake up after this ^.^
