This is exactly the kind of idea that twinkers can latch onto and support. If you're in the EU, please take a few minutes to consider the proposal and add your support.
One of our favorite mistakes as twinkers is to ask for (or even expect) twinker-only solutions. We're lucky that Blizzard even offered us an XP-off option. And on very rare occasion, Blizzard does do things exclusively for twinkers. But much more often, twinker interests only get addressed when they're part of a larger issue.
Dumbing down the gameworld and making questing boring are perfect "larger issues" to tackle. By reintroducing orange and red quests into the game, players can enjoy WoW more, and many lower and middle XP-off brackets could gain some new gear options that would help those brackets.

Well done.
