65 second gens, moonlight offerings, Claudettes hiding in plain sight, 12 second heals, old We'll Make It giving you God Mode with 300% faster self heals, more pallets, double shack windows, slower pallet break speeds, no breakable walls, no bloodlust, super slow window vaults for Killers, could not kick gens, no end game collapse, key allowed all Survivors to escape after finishing 4 gens, Exhaustion didn't exist and meant old Exhaustion perks were on a simple 40 second cool-down and could be paired with each other and used multiple times in chase, instant double heals with syringe, instant blinds with odd bulb, literally instant gens with old brand new part, and lastly, literal infinites that made it physically impossible for the Killer to catch a Survivor. What did Killers have? Instant moris, no basekit Borrowed Time, no anti-camp feature... I think that's it. It was a sad time to be a Killer.
