"Nevermore" need souls after every respawn. He died almost all combats. that's why he was away of the team because he had to farm souls.
Despite the psychological pressure placed on him.He tried to join combats and defences. Plus, he even tried to ward the map. Moreover, I have watched one another replay of his "nevermore" game. He is playing exactly the same. He has high psr yes but we cannot expect him to play perfect with every hero.
The another replay that I have watched.
