Permanent XP boost

If you add a permanent xp boost (like the 'Discovery’s Delight) can you please add an option, where it can be switch on and off?

Every zone in the game and the quests in those are well balanced, that when you are done with one zone, you are exactly the right level for the next zone. This boost destroys any balance, and either makes you dump quests, or being forced to do grey quests. To me it takes all the fun away of experiencing the game. If i don’t have fun playing a game i switch to others, where i can play in my onw time, not being forced to rush through it. Also that boost is pretty much counterproductive to what ‘age of Discovery’ wants to be.

It stops at 25 so just get to 25 and it will turn off automatically.
