@Grinner - you make a good case that the 10% experience bonus is not that great. I'd be more concerned but Wisdom is already probably the best ability with the increased starting aeons that you gain. Still, it makes me think the experience bonus could be increased without breaking anything. Ie, % equal to your Wisdom. As you said it just speeds the leveling process, it doesn't increase the level cap so eventually another character would get to that same level too. Something I'll consider tweaking in the next update.
