>MC being a stupid moron
That shit about being a good boy and all that crap that would only lead to him being scammed over and over. Also, not acting like a proper adult with that age. Seen several isekai with MCs supposedly having 20+ or 30+ years old and acting like 15 years old dumbasses.
>Having the same problems/conflicts over and over
Basically "good" guys betraying them over and over; they have assasins/adventurers/soldiers being sent to kill them but still trust the big bad guy; they keep shut about saying a thing to their allies about the big bad guys betraying them (usually the event that comes right after being isekaid despise these new companions showing over and over that they're some very trustworthy people, etc
