Power shift Celeste to m1 skill expression, revert fire rate changes, reward for precise ball hits, stop moving her power to ult, its boring, let character to be playable themself, not with autowin ult button.
Since Haze got her ult gutted and it's much harder to hit now... if you want her to be an assassin, make it so that her Smoke Bomb spotted radius is much lower. Otherwise, with such a reduce ult, someone buys a single item and boom, her ultimate is pointless.
