How should I play Aatrox
So I tried new Aatrox yesterday, was pretty fun (at least since I was able to bully an Annie and Yasuo early on), and felt good and felt like I could do some serious damage. The problem is, I thought my damage was going to transfer down the road and I was going to deal around the same amount, but I found that I kept getting CC locked (hate Soraka) and I didn't feel very durable (I for some reason thought my healing was going to be Darius levels but found out that my healing wasn't even comparable to Rhaast (and I was used to Aatrox's heal on old W))
So my question to those who have a few games of new Aatrox under their belts, what are the optimal items (which ones are a must-buy every game) and how should I play him when the early/mid game is over?
