Only one line in your post is complaining that his character idea didn't match what he played and that can be a matter of taste, some media anime, it's anime. Usually isekai shit. will cite a character as a melee fighter, but also have access to all kinds of magic to make sure they are powerful.

That line aside, your post was complaining about how he played his character, with half of those targeting the actual player and not the wizard. As to why people are fixated on the blade singer part of your post and not the character concept? It was the first thing you complained about after metagaming.

>tl;dr
Just cut the player. He sound like the kind of guy who will jump from one build to another, like moon druid barbarian or twilight cleric.
