Free Runes: Good. Idiotic Runes: Bad.
When Keystone masteries were first introduced, they were advertised that you would be able to pick the keystone that "fits your playstyle"
Yeah, right
It didn't take too long for the entire community to realize that Thunderlord's was the strongest, so every champion would run it and if you didn't, it was almost considered trolling.
So when Riot says new Runes will make "Pre game choices matter more" , I don't believe them. Just like the Keystone Masteries, the pro players will figure out what is the most efficient Runes possible.
The only difference?
Judging from what I've seen teased here, the new Runes are going to have so much random shit thrown together that it may take a few months to figure out, but eventually it will be figured out and everyone will be using the same stuff.
Keystone Masteries don't "adapt to your playstyle", they tell you how to play. You're using TLD? Hit them three times for the most efficient trade possible and back off, otherwise it's inefficient. Grasp? Attack minions for a few seconds before trading. etc
Another thing I'd like to point out: In the Runes Reforged video, Riot said something like "You can also take Overheal (the rune) if you have a Soraka on your team" - I don't even consciously think about the healers on my team when I'm buying Spirit Visage, I buy Spirit Visage because it synergizes with my champion and I want MR. Similarily, I'm not going to forfeit stronger early trades with Veteran's Scars so I can get the increased healing of Runic Armor because "I have a Soraka".
That level of "complexity" that Riot is going for just... doesn't exist.
in my opinion
, a stronger ver would just make him cancer level annoying.
's with my Crit 

.
Highest winrate build is no joke:
. (And yes that is a Zhonyas, I'm not making this up.)
(last two depend honestly, I like 100% crit but if you need sustain then do it.
