Comments of chapter undefined of A survivor's life in the dungeon. (Danmachi fanfic)

This is genuinely awful, garbage, trash. These are people who have been in the dungeons for years seen so many die and killed so many as well yet they lose their composure so easily and make so much mistakes like beginners instead of doing tactics they blindly attack the monster while having to protect people letting them fall like domino’s and putting everyone in harms way how is this written this terribly? Even if this were to be too strong they should have been privy to the fact they might need to sacrifice themselves years earlier but damn I’m out faster than the flash can run across the world
