I just had a run from Hell. Fire > Thunder > Thunder as a Water team. I started the Thunder mid-boss with my Soul at 70 Burst (due to high damage in the previous wave), so I couldn't Burst right away, and one of my DEF debuffs misssed, so I ended up eating 2 Overdrives and losing one of my DEF debuffers. Then I go into the Final boss, and get so much lag (several seconds after each action) that my debuffs were falling off even with the fixed timer. Each of my debuffs were missing one-by-one over the course of... like 6-7 applications. Usually takes 2. Finally Black Propaganda missed during Rage and it looked like that might be it. I somehow STILL cleared it, but the battle took like 25min.

I'm not even sure if I should try another run. That lag was serious sabotage.
