Comments of chapter undefined of Viajante Witcher - SI AU

The story is pretty good so far, so I don't want to criticize. But are you telling me that a reincarnator with Dnd talents and over 10 years of learning magic was absolutely useless in the potterverse? (Not considering him adopting harry) and the first big Thing he did was help fight the ministry and he died? If he didn't go to the wither world he would be one of the biggest embarrassments of the recanadores. And why the hell did he take Sirius out of the way and take the attack instead? ? He already knew this would happen, he could have simply transfigured a wall in front of him... of steel.
