mecha malphite (granite) chroma

to be more especific you should know that when mecha malphite uses his W he rise his fists up and then he lower them a proceeds to take out a pair of brassknuckles but currently if you use the chroma pack he doesn't do it and he has some problems too with the animation of his passive. i just want to know if someone from riot can review this problem and search for a solution this is the best way i can explain it
