Review Detail of SkiIIzrock in Legendary Armament Canon

Really enjoyed it until mc started doing stupid things. Mc was cautious and smart, not showing his strength or secrets until one arc where he stopped going that... He shows off a skill and immediately gets targeted by an entire country because of it. Then he decides to not bring his good weapons and can't beat someone because he has a trash weapon... His personality changes because of a skill he gets and so now he's not as good of a character. This is annoying, lazy writing, and the reason I'm dropping the novel on ch 283.
