A Gamer Challenge Fucked Me Over

Warning Spoilers!!! I am unsure if I Like or hate this novel, but it has generally infuriated me. It keeps breaking established rules. Why can she one shot insta kill being 700+ levels above her, why even bother with a leveling system. You had a plotline that you could follow but ignore it and throw it away by yeeting her into a different world. You twist her personality extremely, essentially having the system indirectly controlling her actions. This could have been so good. Tone done the slaughter arrays, don't just spawn her into the world as the legit greatest rune mage in the HP verse. I like the lay line twist but tone down the power. You already have a nice plot, make the centaur elder and unicorn lower level, get rid of the Universal travel entirely for now and boom perfect. The first plot would now be she iIreborn in the HP world finds a lay line, slice of life building her home setting up defenses and learning rune magic. Then eventually a centaur elder gets caught up in one of her formation and dies and thus we have some action and you can further build upon the world and the consequences of the death of that centaur elder as she grows stronger and protects the leyline for 200 years. But no.

villain mc with no warning tags - thinking of people as toys - setting up mass killing arrays ect trashy summoning/world traveling system no common sense it's like im reading something written by a child - lets make a house (cuts down trees) why not just use transfiguration mind palace ballshittery - lets sit down in an open space for 2 months opps... i forgot to eat/drink with no outside indications of this
