This is pretty low-tier honestly.
Every player he meets loves him or are comedic fall guys to make MC look better.
The PK characters are worried about the PK penalty. The MC proceeds to PK them (He had his pet half kill one of them, e.g. He struck first, which should flag him as a PK'er), and receives zero penalties whatsoever, but still got to fully loot their corpses.... What?
The only person he parties with goes nearly love at first sight. Is also perfect wife material.
His school "Professor" says he's a completely terrible student that never attends class, but then instantly believes everything the MC says and agrees to give him perfect grades in exchange for nearly meaningless results. (A high level character in an MMO? Seriously? In what world isn't account selling a thing? Heck the MC could be just lying out his ass and already has a high lvl char)
In fact the entire setting of him being a student is absurd in the first place. From what the story has actually shown us, he never even leaves his room at all. He practically lives in the game pod, only leaving it to eat/shit/sleep and rage at the game forums.
The pacing is all over the place. Massive jumps in time, place, progression, level, etc.
The MC is never actually in any danger. I mean, he keeps saying "Oh. they guys are dangerous and can nearly one shot me!", proceeds to solo clear the entire dungeon with little effort. Every. Single. Time. zzzzz
The whole premise is kinda a joke. His class is bad because is "levels slowly". Yet at every single moment where others would comment on his leveling speed, the only response is "How are you leveling up so fast?". It's also silly that they aren't saying that in relation to his class, but as a general statement of leveling speed in the game itself. It's also kinda dumb that his leveling speed is even a question in the first place, since he lives in the game pod. He straight up makes normal MMO junkies look good in comparison.
Every. Single. Sentence. Ends. In. An. Exclamation. Point. WHY?!?!?!
