I am going to say, it better to not read these comments at all. The enjoyment of watching Will development, deteriorates when you have others views on the matter. Turn back if you haven't started yet and just focus on the manga.
Finally a story which pointed this out : Having vast power doesn't mean girls from here and there will flock on you, on the contrary too much difference can totally isolate you. Because the greater your power the greater the danger that will follow you.
Most other isekai/fantasy cover this by giving the harem some powerup after meeting the mc or mc always meets with already o girls.
@Woofzer that is a matter of opinion, i personally find it very fun to see other people's views on William as a character, and doesn't ruin his development for me. but i do see where your coming from
