Lol new runes
"Create your own playstyle!" LOL no, it looks like a repeat, amplified version of the keystones we have now. Every champion's going to have an optimal rune setup to use that fits their kit (why the hell would I take anything other than Precision on Jinx, or Resolve on juggernauts?) If anything, supports are the only class that supports some truth to your announcement (I can see myself going between Sorcery/Resolve/Inspiration for picks like Thresh, Rakan, and Lulu).
We've more diversity options using the runes we have now. You can opt to beef your stats however you want, from early to late. Scaling runes? Or some extra durability early as needed? More AP instead of MR for increased healing as Soraka? I can honestly say, after two seasons with keystones and having played the game since Season 3, you're only hurting the game more with these changes. You can't blame everything on nostalgia; open your ears and actually listen to your veteran/stronger players in the community.
