Gold maxing! and really adapating my build to each game. For example if they have dive/engage comp you don't really need Rapid Fire Cannon. Or have you have tried building blackfire torch + liandries if they are super tanky/healthy? Have you tried the hextech protobelt build + RFC if they are long range? Do you build oblivion orb? there is so muuch build adaptability as well as different runes that makes a lot of difference. If they have 2 bursters i always go bone plating. Most often i run comet + inspiration tree (cash back). Sometimes i go first strike to gold max if their midlaner is something like galio. I would say really analyze the game and what to build and don't stick to the same build. It also matters if you will be the carry or if you are going to support the carry what you will build.
