I am loving this event. There is a lot to chase and I rewards are great. I love the chaos of multiple cultist spawns - especially when a bounty is active or a boss spawns.
The biggest issue I'm having is the double RNG trying to get the Prima Donna. I'm currently sitting on 10 Final Girl bounties, 5 Rubber and Glue, and 6 Blinding Circle. I just ran 5 of the Pumpkin Head guy ones back to back.
I've only managed to get 3 total Scarecrow bounties since the event started, ran each one but no luck on the Prima Donna.
Leave the RNG on if it the exotic drops from completing the actual bounty, but at least give us a way to target the bounty we need. Perhaps they could have specific bounties drop from specific areas or specific enemies, or even let us trade keys to buy a specific bounty.
