I said same thing on my post about Bully Club (at least, similar)
And shovel’s punch can stagger attacking Rager on Damnation difficulty. And Bully Club’s slap can do that too as far as I remember, the problem is if Rager is second target or third or higher number, you can’t stagger him. Punch can aim to stagger accurately.
So it’s somewhat meme special to me. Normally pushing is superior than slap. Punch is stronger stagger than push.
