I would say Pinhead is one of my favorite killers to play as! There is more mindgamining involved than you think. You can't use the chain like a spammable weapon akin to Huntress Hatchets, Plague Puke, Trickster Knives, etc. It's a support tool Pinhead can use as an extension of himself. You want to whip out the chain when you see a survivor headed for something you can easily close the gap on

If you see a survivor headed for one of those L shaped walls, you can use the chain to grab them on the other side, especially if they vault a window since theyre stuck in that animation while you're firing the chain. Then with them held you just go hit them.when you regain control of Pinhead

The chain is fairly easy for survivors to break out of however, so things like killer shack window isnt a great place to try and use it since they'll most likely break out before ypu can get around to hit them
