I understand Pyramid Head has 0 mobility or map pressure but I think the fact that if you're ever in his terror radius you're at risk of taking a hit makes him very high tier at least.

I've had games on a knifes edge where it swung out of control immediately because I hit two people with one PotD. You can invalidate chases, any animation lock, hit shots that literally nobody can predict.

All my worst games on him are when people consistently respect the TR and prerun like fuck or they actively avoid setting up a good 3 gen. Besides that it's usually quite easy to secure 3k+. Being able to ignore DS and saves on 2nd hook completely is also a pretty big bonus that I feel like most people don't take advantage of. My only real problem is that he slows games down so much that every match takes like 20 minutes. You are constantly putting pressure on survivors and forcing them to make knowledge checks, denying 50/50s and with his Iri addon that breaks pallets you are literally just Nemesis but better in every single way.
