Do people actually have issues with this quest? I usually avoid difficult content like Holograms because it's not my cup of tea but did this one because I accidentally started the quest without realizing what it was. At the end at full buffs it took less than 5 minutes to beat Arsinosa with my Camellya Roccia SK team. Way easier than I was expecting it to be. The event banner itself even has a high difficulty warning on it, lol.
