S9 Rune All Stats Choices

Hello, I find the new stat choices in the runes quite one sided. For example, auto attack champs will always take attack speed + dmg + health, tanks will always take resistance + cdr and casters will always take full dmg etc. They should make the new stat choices in the runes have every single stat e.g. lifesteal, movespeed, health regen, not limit each one to defensive/offensive stats etc. and make gameplay and playstyles more diverse. For example, Yi can pick full attack speed, Renekton can pick full spellvamp, Sona can pick full CDR etc. What are your thoughts on this? Felicitations, The Flying Mojo
