I Hate keystones, especially seasons 8 masteries "cough" sorry I meant runes. Bring back old runes
After adequate time spent with keystones when they were first introduced in S6 i believe, i hated it. It doesn't make "diverse playstyles" it just makes champions harder to balance, especially now more than ever. I don't mind short games but regardless I think these new runes are a big part of the snowbally games. It feels so predictable, say I take Aerie or comet keystone and my opponent electrocute, I can win early lvl trades and poke, but if they play passive for a little while they win. Yes thats how it should be but with 25 min average games this is to pronounced & linear.
I feel that all masteries/runes/keystones whatever name you give it should only be utility based and not damage or defense based. Then bring back old rune system but with buffed numbers since damage and defense masteries would be removed.
It's like they want to save time in balancing champs by grouping champs and balancing runes they use instead thinking it will fix it. Which just shifts power to another group & repeats in a endless cycle.
For there to be no cost to entry I would have runes be free and have them adjustable in champ select like old masteries/ new masteries. Runes would just be level locked like they have always been.
I also dislike jungle plants, they don't fit in, never have Hate the blue essence system Hate the matching making system or however it selects your teammates & who it puts you against
