Riot, just give everyone 2 keystones, nerf every single keystone/rune and call it a day.
Scarra's recent rant on runes is only a hint of the issue at hand, and he wants them removed entirely. Let's be honest: runes from Runes Reforged are ridiculous. Every single one of them - even the 'bad' and least used ones. 5%+ bonus damage from a non-keystone rune ever is absurd. They don't deserve to be so powerful that a unit with average champion stats that is a compilation of every single rune and keystone would be stronger than any champion in the game.
60 magic damage to champions hit by a spell every 20 seconds. +10 Lethality/MPen after dashing. 18% Attack Speed at level 1112. +7% damage to champions at low health, or +11% damage while at low health.
See the problem here? These aren't even keystones - these are just the runes! Keystones are the biggest problems and yet runes are also such big balance issues! It's such a mess; look at all this free damage! No wonder no one likes winning anymore: teamfights last 3 seconds!
Just nerf every keystone and every rune, and give champions a keystone in their secondary branch instead of a second rune. And nerf them hard. No one likes them as they are currently.
I'd rather GP with a nerfed Klepto + Grasp be my biggest fear than bot, mid and jungle being decided 2 minutes in because of everyone's ludicrous damage.
