Just to clarify as I know the system Sikako is familiar with, he is referring to a T3, perhaps T4 character at most, the Pater is T6 with a few abilities that push into T7. It doesn't really have any weaknesses, it can and has lol-dodged projectiles moving at supersonic speeds and above and it regenerates from harm pretty consistently. The Magna Pater isn't mid-tier, not unless half its abilities are nerfed or given hard caps. I think you'd struggle to find anyone here who knows the system who would say it was.
