A real shame really, not that there aren't tonnes of other bosses that can be cheesed in that way. But the way he is just chilling there and you can see the red eyes and everything does make me wonder if it was deliberate. Just like Capra cheese method. Does seem suspect.
I would imagine around 50% of the people currently running around with Pursuers cheesed Manus.
