How does people play this without Cassia?

She's so busted. I've only played those game after she's been nerfed, by my God she's so good, even on Hard. Bc of her perception dodge ability, she dodges everything, she heals every turn, she also always goes first, she can use LG twice in a row, her other navigator abilites are busted...

Like damn, what was she like BEFORE the nerf??
