I think her problem is not having enough perfect supports to help her, she needs a lot of act agains and skill activation rates, but thoses are considered expensive buffs in this game, at least that's how I think about act again and skill act, very hard to get 100% skill act, and act again is still very rare, especially 30%.

But because they're rare, so it's even harder to try to get both in a team with only "5" girls.
