Aatrox's e has bad hotbox

So when Aatrox uses his e (the cone slow cut thing) it carves out a V wight he point being the max range and near the 'point' you get hit almost as if you where at the upper part of the V. This makes it really hard to accurately sidestep his slow , which if you do not dodge you will most likely die, it basically makes a small diagonal sidestep go to running in a completely different direction . Also while Im posting can you somehow make worth it's cost, avarice blade just builds into better items and this item has no really I NEED THIS to it. TL;DR ***Aatrox e needs a new hotbox or clarity check and Executioner's calling is a bad item ***
