Things are easily fixed this way if riot loves their new runesystem too much.
increase MR , Armor, and Health back to what it used to be years ago, buffing all tank stats on items to previous level. Decrease ALL dmg, decrease tanks dmg even more then the other champions. By decreasing dmg and increasing tankstats the game would go back to where people enjoyed it most. And no by doing what i said it wouldn't be tank meta all over again due to as I said decreasing tanks damage more then any other champion pool.
Have fun downvoting me because I know that's what most of you power hungry assassin and adc mains are about to do. [slayer-pantheon-popcorn]
