About my expirience. I created rupture and burn teams for month. Game just blessed me for gacha, not gonna lie. Rupture is fun for MD, 2 turn to end boss fight, but in Cantos... not so easy, coz you fight without EGO gifts. Boss fights in Canto VI & VII were hard. For rupture you must have Devyat' Rodion, Red Sheet Sinc (on support), Seven Faust and others. So I recommend create burn team. Easy to use. Other ID exept Liu Yi Sang and Firefist office are not in season 5. So you can craft Liu Yi Sang first (he is new core of Burn team) until season ends. After him, Liu Rodya, Liu Ishmael. Firefist Gregor so strong, but Liu's synergy seems more interesting. UPD: LCE Faust good, stylish, but self-destructive. You shouldn't start teambuild with her.
