An idea of balancing league ( game rework )

So i was talking with a dude that used to be Master tier before his ban and we were discusing the disgusting game balance of season 6 while we were in que and he came up with a really good idea in my oppinion for balancing out the game. So it goes like this the whole champion Role will take effect as to what benefits champions take from items. For example tanks get 100% of the tank items values and 50% values from dmg and or ap items who are meant for mages and assasins( numbers can be changed by the game developers these are rough example so i dont have to go in depth math xd)

Malphite builds Deadmans plate malphite classified as a tank gets the full 500 health and armor from the item. Maphite builds Rylais malphite classified as a tank enjoys half the effectiveness of the item aka gets 200 health and 50 ability power instead of 400 and 100.

Yasuo classified as an assasin based on critical chance gains full stats from critical items example his builds PD gets his 30(60) % crit and the attackspeed. Yasuo classified as an assasin based on crit buys frozen mallet yasuo gains half the stats from the item aka 15 dmg and 350 health. I believe you got the point so far this will of course kill off meta builds like AP kog(Already dead anyway) or AP corki etc etc BUT will make the game easier to balance(i think?) and we wont have happy accidents like Tank Ekko/Yasuo/Zed/Akali etc etc. Of course with this we need the removal of the lame keystones that broke a lot of champs and we gonna need NEW reworked masteries ( or maybe remove them? )

Now to the fun part: Champion scaling So his idea was that ALL champions start with really low base dmg's but have: Really high / high / low scaling based on their role classification. In other words their benefits from items vary based on their role if someone is a tank he will have shitty scaling based on dmg but they will have great numbers for health and resistances ( maybe tenacity too ) and this will stack up with the item changes based above.( dmg based on health counts for scaling with health and not dmg just like now ) So again this removes the disgusting tank builds from assasins and fighters based on dmg but also as i said before REMOVES completely off meta builds. So if rito finds a way to code the game like this do you think it might end up for the greater good? will it make the game less fun because off meta builds will be unviable? Find out on the next episode of.... wait wait wait wrong outro. Lemme know your oppinions excuse any grammar errors not my mother languange. Personally i dunno maybe with the right numbers it might work out. -Whirlingdeathx
