My solution to the GH3 battle mode issue, keep as they are, but remove the battle power phrases from the opponent's chart, and not the player's chart. Only the player gets the power-ups. Or make it so that the AI never unleashes the power-ups. And the player has to unleash the power-ups before death drain. This would make the boss battles FC'able for the player without the risk of RNG. And miss a note or get to death drain, you lose.
