I'd like to see a Iteration of Force of Nature on Summoner's Rift
After seeing how much MR 3 items gave me, when all i'm looking for is some resistance, 165 was pretty low for the ~9k gold I spent for it, I'd honestly like to see some Force of Nature back in the game, I feel so much more durable in the faster paced gamemode than I do in the mode where Tanks are suppose to be more durable in. (Tanks are Early>Mid game champs as Damage always outscales durability, like it should... but at this point if there's 3-4 ap on the enemy team there isn't enough MR from 1 or two items to save you.)
We still have Frozen heart as the high Armor no HP counterpart, I'd love to see some testing on Force of Nature on Summoner's Rift, maybe check out putting the Summoner's Rift variant with a Unique Passive if stacking it stops becoming so much of a meme and more oppressive, but it would be nice to see.
