Making it more In-Depth (Champion Fire-Water-Wind etc. types)

I was playing Magic the Gathering (who knew) and i thought what if there was elements for every champion, something that buffed or de-buffed considering the champion's element type, for example:

Annie, Ziggs, Rumble = Fire Fizz, Nami, Nautilus = Water Zyra, Teemo, Maokai = Grass Syndra, Bard, Kassadin = Psichic Lissandra, Sejuani= Ice Lee, Jarvan, Nautilus, Udyr = Fighting ( recieves +3.3 resistence for every element) Kassadin, rek sai= Void ( +3.3 damage to all elements) Malphite, Yorick= Ground
Mordekaiser, Darius = Steel Zed, Nocturne, Evelyn = Darkness

Some champion could have 2 element Classes

Counter Example: Fire gains +4.3 damage against Grass and Icy Champions

This is just something that would make counterpicks more fun, and more accurate, just something to think about maybe in the next 3, 4 patches, aint something that hard so insert since no animations are needed, maybe just icons, easier than champ masteries i mean. Cheers
