You need to have a fast enough team to do it (max 4 turns burst cycle). if your team is as slow as mine (Tishia, Eros, 2 sr - Diana + Attar? and no Mike, the only aviable way to speed up is Shingen), you definitely can't spam her s2. It's the same as Diancent - she is as strong as fast your team is.
Yes, Eros + Mike is 40 bg on debuff spam content after burst, but Mike is a key.
