Comments of chapter undefined of Omniscience in Marvel

This guy is supposed to have two cheats, but because of the steady development you want to give the story you neglect the most important cheat of all, thus leaving lots of obvious loopholes. The cheat I am talking about is his experience as a God with the 3 O's, especially Omniscience, cuz even though he does not have it any more, the knowledge he would have gained in his years should have been able to help him even more than the intelligence now. I mean why does he need to learn when he already knows all these before and you can't say he does not know it cuz he had omniscience before and you can't tell me he never once thought about the intricacies of science and energy before, so he should have knowledge of all this and not acting like a normal Mc that was suddenly transmigrated into the marvel verse. In short, the steady development you want to give him has been spoilt by his background as a God, you forcing it now just leaves a lot of loopholes in the story.
