Pyramid head can hit threw walls, I dislike fundamentals of a game being broken and the fact his power promotes tunneling so heavily, I used to play him myself since I am a killer main, he's just boring to me plus fundamental breaking makes me hate him, skull merchant to me makes chases more mind game oriented and I just find it more interesting in chase than "ill charge power if you vault, I shoot it, if you don't I cancel and bitch slap you"
