Honestly, I think it would better to only absorb a small fraction of the Aether, so that instead of gaining godlike abilities, it instead levels up all of his skills, particulary pain tolerance and healing factor to max level, same with super strength and speed. maybe even super durability if he absorbs some of Thor’s powers for example.
It's stupid to use a potentially limited resource like automatic skill increase this early. If a skill leveling up boosts the power exponentially then it's only logical that the experience required to lvl the skill ALSO increases exponentially. He should have kept the auto-lvl-up for going from 9->10.
