It's one of the better generic ones so far with very few points sticking out where someone could hit their toes. Pro: MC works for his skill and doesn't get it presented on a silver platter. Con: MC is completely dense and oblivious to his actual strength. I hope that this will resolve quickly and it won't turn out as a running-gag that overpowered MC thinks he's the weakest. I hate this trope so much.
