A way to make Omnistone an actual rune.
Make it so when you pick Omnistone, once your in game, you pick 2 keystones and thats it. Those are your runes. 2 Keystones together without any other rune may seem harsh, but just imagining it makes me shiver. Imagine all the combos. Conqueror plus Phase rush Darius? This would make the rune actually good and not a piece of trash garbage.
