I got around 3309 with my JingYuan-Tingyun-Sparkle-Galladger e1. The trick was to use tingyun ult into galldger in order for galladger to break cocolia much quicker(Like actually you use tingyun first ult into galladger and use galldger ult immediately to break cocolia before she spawns her stuffs). Like you already get so much energy from getting hit so tingyun can still regen her ult fast for a consistent 10 stack ll. I am pretty sure that I got has been faster since I got cc once on JingYuan. Sad on not having e2 Galladger. As for second side, I use DrRatio-Pela-Aventurine-RuanMei. There is a trick I used against Argenti. Before he spawns his stuffs that make him non targetable on his second phase, I used up all my DrRatio ult-Pela ult-Aventurine ult for a really big break. Saving up their ult for this moment is really important. I got around 3550 for the second side. Overall a fun mode but RuanMei and Galladger did feel a bit more mandatory here.
