Roccia's range is a lot higher than camellya's, she guarantees that nothing will escape the spin even if it spawns after she leaves. 200 flat atk is around the same as 20% for camellya anyway. and no outro amp in the game outside of healers is longer than 14s, and you can double intro and it will be optimal. Nothing there is wasted, there is no anti-synergy at all. If it does 20%-30% more dmg than the alternative (no sanhua) no one would say she isn't by far the BiS for cammy, or expect a character with even better synergy later.
