Jayce switching to melee form lag

Whenever you switch forms into melee as jayce there is a lag spike for multiple people in the game. When i played jayce i was in a 5-man and all of us lagged when i switched to melee. This bug happened everytime i switched into melee form. Also when there was a jayce on the other team my friend and i still got lag spikes when he switched even if we didnt see him on the map.
