The tower changes are just Riot slapping you in the face twice.
First time was not even bothering to change Yasuo or Tryn or any melee AD really in preparation for the item changes cause that would actually require work, and the second time was making it so these champs can now take towers almost instantly, turning split pushing from an annoyingly effective strategy to you might as well lose both side inhibs if your top gives first blood. Can't wait to see the patch notes for 5.23.
Guys Yasuo seems pretty broken, so we're going to cap his max damage to baron to 500. We feel this will make him less toxic. Fills you with determination :P.
