Infernal amumu ult

I love the infernal skin and the chromas, but many times in a game, i will ult- in the infernal amumu chroma- the color of the ult is very dark and doesnt really call attention, and also makes almost no soumd, so if i go in for the game changing play and ult, most of my closeby teamates dont recognize the ult. = I die, the other team escapes my cc, my team loses. Plz help thanks... as of now i get better results with the other "OLD" amumu skins 😣
