Play a game where no one chooses Runes. The Game becomes balanced again.
If every player on a team does not take runes in a game, the game becomes surprisingly balanced again. Damage falls hard, defense starts to matter really well, and strategy returns. Really, Runes Reforged is the thorn in the strategic aspect of this game. It makes or breaks metas as we have seen since the start of season 8. Get rid of it. Neat idea for a while, but it destroyed the health of this game.
