Every argument about Superbolide's health drop being fine fails because Hallowed Ground exists.

The HP drop is only there so it can be different. There is no advantage to it, there is no nuance to it. It's just a weaker Hallowed Ground, that's already a weaker hallowed ground by virtue of Duration, so having it being weaker than Hallowed Ground with a health dip too makes no sense.

If the Gunbreaker had -anything- that would play off off this 1 HP state, such as an Ability that's fueled by -health loss-, it might have a leg to stand on.

But it doesn't.

The -hp drop can only work against you, never for you-.

But it could be worse. It could be Living Dead.
