Dying Light literally buffs the Obsession, and completely stops working if they're dead. Below average in conjunction with Michael's other perks, borderline useless without them.

I find Play With Your Food to be too easy to lose stacks with to be any good. Sometimes I'll use it on Wraith or combine it with Hag's Waterlogged Shoe and other Haste perks, but at that point, I'm not playing to win.

Save the Best for Last got absolutely gutted to the point that I don't think it's worth running on most Killers, but it's still nice on exclusively M1 Killers who don't really have other means of building pressure.
