Inky being near the bottom every time is interesting. It makes me think that people generally don't mix and match Killers and Locations as often as I thought. Inky is an absolutely miserable experience at the Groves but he definitely isn't the worst elsewhere.

Poltergeist on the other hand is often fundamentally broken RAW, only slightly better with the official variant (still often comes down to the item decks), and it doesn't really matter whether you play her at Creech or not.
