We talked about this post just now.
We are going to extend the exp boost for the entire week.
Long term: We are also going to adjust the experience curve so the higher levels aren't so frustrating. (Starting with 1.2) We also also going to put in daily quests in the next major patch which will give experience bonuses to break up the monotony. (Patch after 1.2)
