Hey Riot, maybe adapting to lane matchups should be itemization, not runes?
One of the concepts that I feel like won't come through as intended is the idea that you change your runes to adapt to your lane opponent, at least as far as defensive options go. My reasoning is that only Resolve and Sorcery have runes for that (Iron Skin, Mirror Shell, and Nullifying Orb)
If you feel like picking one of those is so vital that you switch a secondary tree that seems like it would feel lame and disempowering. It's a huge change of your strategy. You give up fun synergies with rune combos you want because you feel forced to from a bad lane matchup. That's entirely a different thing than switching your hp/lvl seals for armor seals or something like that.
So I think it would be great if level 1 itemization was updated to take on this role. Level 1 itemization isn't exactly interesting right now anyway.
