110 Questing has never scaled with ilvl, and Blizzard has said repeatedly for months that that's intended. If you didn't know that you only have yourself to blame. Questing gets much easier once you get to 820+ ilvl, and the rewards scale with your ilvl. Once you're 835+ dungeon world quests can drop 840+ gear. Got an 835 relic that Titanforged up to 850 from a regular ass world quest.
The quests are plenty rewarding.
