Because you need high investment for relic especially Seele and Sparkle relic. Mine is E0S0 and can clear the first half with something like: E0S0 Seele, E1S0 Sparkle (wind DDD), E0S1 Robin, Huo huo (3 cycle). I'm really sure I can get 2 cycle if I have her LC. Also, I always got 40k PF for both side with Seele since I got Sparkle and get stronger after I got Robin. But you need to know when u should use skill or BA.
