KC does have a bad durability, but KC is basically STW 2.0 because of its ragdoll moves. KC's ragdolls can be punishable, even its combos are super deadly against Stands with a B or A durability. The best KC combo I've had is R + Y + H + (E if the person is not dead.) No joke, R + Y + H + E can kill a Tusk Act 4 user in less than 4 seconds. KC is just underrated and overpowered on pvp, but people are just focusing on other Stands so much, that normal KC is a forgotten overpowered Stand.
