Object is one of the best perks
It really is crazy the amount of information you can get from what you see (or don't see) with Object.
Who's the Killer? You'll get an answer within the first 45 seconds of the match.
Tinkerer? Unsurprising. Blood Warden? Unsurprising. BBQ? Unsurprising. Undying? Unsurprising. Nurse's Calling? Unsurprising. Dark Devotion? Unsurprising. I'm All Ears? Unsurprising.
Not to mention the variety of ridiculous Killer add-ons like Glowing Concoction, All Seeing- Blood, Black Incense, Myers Mirrors, Vigo's Journal/Compound 21, Cigar Box, Renjiros Bloody Glove, Silencing Cloth etc.
Auras and Undetectable get the majority of their value from Survivors being unaware of them and Object blows that advantage completely out of the water. An Object user won't even be tricked by them the first time, when pretty much every Survivor would at least suffer a free hit before they learned. It's not for newer Survivors, but very worthwhile for Survivors that can really triangulate with it and don't mind being chased.
