That moment you realize Last whisper is efficient at every situation.
As the title says: Last whisper is extremely gold efficient at every situation. Just look at the graphic taken from League of Legends wiki: when beyond 200 AD (which every AD can reach at mid game), Last whisper is gold efficient even against targets with 50 armor like a Syndra or Tristana could be.
Last whisper shouldn't be core item for every marksman to work, Last whisper is supposed to be a situational item you'll pick if an enemy is abusing stacking armor, but currently is a staple on every marksman build, even against teams with no tanks.
I can't say anything more, since I have no idea how this item can be reworked to keep its original purpose without making it a staple on every marksman.
is currently the item Riot is using to ensure games end. Completing your IE/Shiv or PD/LW triple is intended to be a huge power spike that lets you force objectives if you get there first.
give by a significant amount so the focus of the items are on the actual penetration they grant the buyer.
