Hey Riot, here's my feedback on the rune changes from someone who has been around from the start.
hey! first off I want to say that this update looks super interesting! I honestly am excited for there to be a serious rework of runes, I can't really remember runes being balanced aside from removing dodge, some price changes, and that terrible idea of tier 2.5 runes (sorry, but that was pretty bad lol). I'm excited for a large amount of choices that will let me fit my playstyle to the enemy team in select! I was thinking that it might be like keystones where everyone just picks the same one always on most champions, but when you mentioned things like overheal and how it might synergize with the other champions on your team like Soraka or Sona, I realized you guys had made some amazing design choices. Instead of only letting you build your playstyle around yourself, it looks like we can form playstyles as a team which i'm super excited to try out!.
One thing i'm a little worried about however, is how these all might be implemented and remove previous options the current rune system has that I enjoy a lot. I sort of like the primary/secondary rune system and while theres a most efficient way to make your page, I like foregoing that entirely on some builds and going all into offense or defense. A good example of this is Silencee's full crit master yi jungle in which he takes no armor yellows or MR blues and pumps his page full of attack speed. It gives him a very unique option of getting a zeal item and then 2 AD items while maintining a respectable amount of attack speed, all while being incredibly squishy. It's a super fun playstyle that I enjoy. This, things like full AD page pantheon, pre-rework galio going full flat or scaling MR (rip in pepperonis 45 AP/80MR lvl 1 with no AP runes), and putting a little bit extra attack speed on your ADC page vs little to no magic damage threats. I hope that you will keep these fringe options alive with the new system, its important to me as a player.
Regarding the honor system, I think tying unique content to the honor system that is actually desirable (not just an icon or something) will seriously boost positivity in League. I won't lie, I had a big history with toxicity and how I played the game while growing up and going through rough patches in my life and am no stranger to this game's player behavior team, I can honestly say that I hope I can show reform with some shiny new rewards and things through the new honor system! More feedback to come once I see more info on the changes, but these were my first thoughts!
