The new turret plating should change color based on the laner's previous season rank
Imagine this..
"Welcome, to Summoner's Rift"
You hear the rift theme, it fills you with anticipation for the game to come. You rush to your lane as you pass by the circular bedrock, the stone begins to surge; a mysterious statue of a sorcerer begins to take shape, its wand glows with your team's colours, and then as it greets you, a great shield emerges to guard its torso, as it settles on the stone, you see the metal, the finest bronze in the whole of runeterra.
