The Gregar fight is so true. While he does his patterns fast, they are both fully predictable and easy to dodge. I remember doing buster only runs back in the day. What a joke of a boss.
It's even worse that he has 2 hotboxes so piercing attacks do double damage and he can be easily countered by the guard chip from his breath attacks. It just didn't feel like a final boss once you understood the pattern.
