No Dark Side GL can efficiently counter a JMK/CAT/GK/GAS squad.

Maul is way too complex for the AI to handle. Sometimes you want to use all 5 Anguish to kill something. Sometimes you want to use 2 to increase CDs and have 5 stacks for next turn. Sometimes you want to use Anguish strategically to let Maul get a kill with his AoE. Plus you have to decide who’s cooldowns are increased. Any of these have potential to flop big time.

JMK + CAT the only choice is who is erased from the enemy team. And while there’s certainly some optimal hits, there’s not really any wrong choice for the AI to make.
