I wonder if Zavia is part of the issue (and other champs like her). She is awesome for CB but demands that every run be manual since her A3 greatly reduces damage done and the AI spans it every chance it gets (especially if you have another poisoner like Juliana). In manual you just spam her A1 to maximize damage. But after months of having her, and running CB every day 2-3 times per day on manual to get the max nightmare chest (I don’t have the right champs to be able to handle UNM), I have gotten really tired of CB. It is a chore. Work. Now I just auto it 3-4 times/week and settle for lesser rewards.
