.... Since when has this series been "wasting 50 billion chapters"? This has only been two chapters and we've had a lot of character development happening here, and that was particularly thanks to this party's healer, Shinonome. But I guess that's not good enough for you because you seem to feel that it's gotta be the MC waving a big dick around, all day every day.
You see, that's not the composition for a good story. Because a good story allows other characters to have their own traits and qualities show. And for that to happen, that means that the MC can't be hogging all the limelight to themselves.
And I really, really dislike it when people like you get like this. It's like you're that kid from the movie, The Princess Bride, where he interrupts his grandpa telling the story every time the "kissy stuff" pops up. Except where that's actually funny because it's part of the story, this is just plain annoying.
I'm not saying that you have to like the story. But if you're gonna critique and complain, then have an actually good reason that is an actual reason, and not just some ill-perceived idea based on a warped perspective.
