The last whisper is just absurd when you already have 45 armor pen. If a normal squishy has about 90 armor you're already getting them to 45 and then your last whisper is reducing like 18 armor. Useless. And that said, saying a squishy has 90 armor is APPARENTLY being generous considering you have only 70 of both armor and MR in this build. I think armor per level yellows and mr per level blues would serve you better if you insist on not buying defensive items. But as for replacing the last whisper, I'd suggest an infinity edge if you're looking to hit harder. This build already has a respectable crit chance and the extra bonus along with the AD would help a lot more. Not to mention the excellent 250% crit damage

This guide is really boring, make some color and some pics.
