Adaptive defense?
We have adaptive force, so why not? Imagine if instead of armor or magic resist items just had adaptive defense and when you buy them you get to choose whether it turns into armor or mr? then like once you choose you have to sell the item and re-buy it if you wanna change which stat it has. I'd love to see a knight's vow but with magic resist, but I don't think we're gonna get it. Riot always says they'd love to add more choices for players but they don't want to overload the shop and make things confusing for new players. I think this would be kinda cool. Of course it would work the same way adaptive force does, armor and magic resist would each have their own respective values, they wouldn't be worth the same amount of adaptive defense. I'm pretty sure armor is worth a bit more gold than magic resist is (1 armor = 20 gold, 1 magic resist = 18 gold) so maybe adaptive defense would be worth more magic resist than armor? Kinda like how adaptive force is worth more ability power?
