While I agree with the Yi and Shyvana, I disagree with your last statement of all champions that use it falling off. Mine doesn't, it's insanely strong early-mid on the champ I use, yes, and if I get more than 5 or so kills before 20 the enemy team is in so much trouble. I also find that as the game goes on I just become more devastating unless they all just stack pretty much every armor item in the game. If they do this I just grab a couple tanky items and split push like a monster.
However I will say if I saw a Master Yi or Shyvana go warrior now, sure I would probably say WTF too. The champ I use isn't any of these FotM though. I'm not trying to be secretive and it honestly isn't that big of a secret, but my entire solo climb from silver 4 going on Plat 3 has been this same champ using Warrior (It's not this account). I can honestly say 9/10 games I can pretty much wreck anyone on the enemy team and snowball at least 1 lane very easily. Does this always equate to wins? NOPE, but it's got me this far.
Good post though.
What I am trying to say is that Warrior falls off late game. It is not the champions who use it. Warrior falls off because it only offers flat armor penetration and has nothing that can scale well into late game like Runeglaive, Cinderhulk and Devourer have. However, flat penetration is very good for early game where enemies do not have a lot of armor and magic resistance. Also, most champions who use Warrior are champions who have an extremely good early game, a somewhat decent mid game, and then fall off when late game comes. Examples include Lee Sin, Jarvan IV, and Vi. Before patch 5.13, the reason why Master Yi used Warrior, was not because he had a poor late game, he actually has a very good late game. However, Master Yi was forced into using Warrior because Devourer was too much of a late game item, and didn't actually offered that much. Shyvana used Cinderhulk because she is tanky and had better synergy with Cinderhulk's tanky stats, but she makes better use of Devourer right now due to scaling much better with it than Cinderhulk.
To be honest, Warrior is the only enchantment that actually falls off late game. Every other enchantment scales well into late, except Warrior. I hope that Riot adresses that issue.
