I really am looking forward to more, but I'm also going to wager a few tropes are going to be involved in this scenario. For example: Earth is a Low Mana World, which is why things that typically get treated as the most casual skills cost massive chunks of mana. And Mana Fatigue, which we've already seen, thus treating basic skills as huge causes of strain, worthy of being granted experience for.
My main hope is that the series doesn't jump onto 'maximum exp gain' traits, where he wakes up at level 100 with every skill unlocked, which leaves very little room for the character to actually grow.
