The problem with the new preseason runes update.
Riot said in its recent rune update that they will add base stats to the champs to match thier "role" which is very limiting since it will destroy offmeta picks entirely. We saw that sometimes offmeta picks are very strong and fun at the same time (mf support, lulu mid, etc...).
So what im suggesting is that beside the rune change, add us another page or add another rune slots where we can choose which benus stats we want, that way we add more diversity to the game and not make it limiting. Since the role is a concept made by the community and can drasticly change over time.
