I'm duly aware of all that and yet, still doesn't refute my claim in as it's intended purpose. Can it be improved? Sure. But taking away its intended purpose just to do so is....silly.
Hell, they could just make it that a hit doesn't eliminate the buff and only a throw attempt does, but don't allow the buff to stack outside of holding it, as otherwise, it'd be all too good.
What's the point of clinging on to "intended purpose"? If something can be changed for the better, I don't see how any of that matters. Nothing should be off-limits if it'll make for a better design.
