Building Frozen Heart AND Iceborn Gauntlet on Ryze?
My usual Ryze build for facing a FULL AD TEAM. = Tear, ROA, Sorc shoes, Frozen Heart, and WoTA. After this, would you recommend an Iceborn Gauntlet? The extra mana seems fantastic, and the extra armor seems like a plus. but I've heard that the more armor you build, the less effective it will become. So in that case, should I instead build a Void Staff? (Keep in mind, in this scenario, I'm against a full AD team. If they had an AP carry, I'd obviously build a Spirit Visage or Banshees over Iceborn.)
Thanks for reading, any and all advice is appreciated :)
