The more I see the mc refer to his character as 'trash', the more skeptical I get. Like, yeah, he could have focused on a specific path or job. But characters can be all-rounders and still viable. We can see that here for instance (if we disregard bs mc plot armor), he is able to succeed regardless of the fact that he didn't focus on a single class. It even helps him in that case since he can do so many different things
