meridis got it right. all the alterations of isikai have the same problem and authors only try to change in superfically. another world with a class, another world with x skill maxed out, another world where everyone hates MC, another world with a weaking-psyche! his power is that he has all the powers plus one that nobody has and others stemming from his ability to combine the normal powers!
they mistake personality with tragic backstory(NTR, dead loved one.)
