"It's inconvenient to you."

That was one of the issues Minato had with it. If any of them were injured, Minato couldn't heal them. Even with the past event where he also thought he was part of the Shinsengumi, Minato couldn't stop thinking about how useless he was. He really couldn't do anything at all. Not anything helpful, at least.

If he could just summon without his Evoker, like how Souji was able to summon just from his soul alone. It wasn't a comparison game, but he could see the drawbacks.
