R68 AI Cascades

The AI in PvE is really getting extra cascades. Here is what I have noticed:
1. AI with active characters, characters that match tiles. The AI gets on average 2+ cascades from the top of the board, meaning that cheap AP powered characters such as overpowered 1* Venom and Juggs get a huge boost. I have lost several matches to Venom because the AI was able to get perma stun from match + cascades
2. Against AI with active characters I get less cascades, multiple power use such as Thunderous Clap, Lightning Strike, and I Am Groot will not trigger a single cascade. This is very different from when playing against grunts, prologue, etc.

In the past I have chalked the AI getting more cascades to luck, but in several matches after 4-5 uses of board clearing abilities in a match without a single cascade, this seems very very unlikely.
