Yeah i think her Abilities are a little bit underwhelming compared to other 6*...
Most 6* Girls buff Atk for the whole Squad (She buffs 18 % to 4 Members including herself) and the Dodging Ability i would consider to be decent (i could be wrong in this case cause i don't have that much experience with dodging Girls. I only have Water Lily. She is good though)
In my opinion:
Design: 7,5 / 10
Power: 7,5 / 10
I wouldn't complain if i ever get her through luck though
And speaking of Step Up Gacha: I prefer the Gacha Variant cause it's 10 bucks cheaper and we can roll a 10+1 there ( Yeah i know RNGoarsi could betray us there )
