HS -> Maim -> [Brutal] -> Eye -> [Pot] -> HS -> [IR + Berserk] -> ??FC -> [Infuriate] -> FC -> [RI] -> Maim -> Eye -> HS -> Maim -> [Brutal] -> Eye -> Fracture -> FC -> Pacified

You have 3 abandon here, how are you getting to 5?

Furthermore, even MT you can easily do something like this and not worry about mitigation:

HS > Maim > Eye > HS > SS + [Pot] > BB + [Deliverance] > HS + [Berserk+IR] > FC + [Infuriate] > FC + [Raw Intuition] > 5x combo > FC
