[2021] Nevarro: Scoundrel GC - DOTs Feat Not Counting

I count far more than 30 DOTs: https://www.youtube.com/watch?v=IlBXIhRuwds

I'm sure I could use another team for this, but how is it that an obvious team (given the BH bonuses) doesn't work?

I have to assume it's because the BHs aren't actually applying the DOTs. The enemies are applying DOTs to themselves when they get critically hit, right?
