How to make each game feel unique

Riot is trying to add diversity, different ways to play the game (playstyles) to make each game unique but they always fail .My suggestion is to make the rune system where you can choose 3 rune keystones and 1 or 2 small runes from each path you chosen ,and ofc the runes would need some tuning(mainly nerfs) but i feel like each game would be spicy and fresh .Write your though as to how riot can make each game feel different.
