A few things I noticed from looking at your match history:
- the playstyle between the champs you've chosen is extremely different from each other
- your CS numbers - if I may, with very few exceptions, they're disgustingly low.
- Your builds - they lack deviation based on enemy lane and how to maximize your potential both in lane and in team fights, I'll revisit this thought later.
Particularly; I noticed Aatrox. Your game vs Singed top went fairly well for you - you were able to take advantage of your early game against Singed and suppress him. However, your game vs Wukong went...not-so-well, to say the least. I think we can agree on that. While, it's a difficult lane, you still have a nice advantage with your sustain and utility that you bring, and you're manaless. If you're zoned out early, remember you can always farm under tower.
On that lane and that particular game, the build was fine but you lacked the early advantage and you probably saw how that followed you throughout the game, it tends to on Aatrox.
Back to the singed game though, and revisiting the thought of builds. While I'm not going to say you did any bit badly here, you didn't. However with the sheer amount of CC and magic damage being cranked out on that team - you'd have been better with Merc treads over Ninja tabis. Caitlyn and Sion were both behind enough that the tabis wouldn't have helped much against either where the Tenacity passive of Treads would've.
Small changes like that can make a huge difference in the game rather than hanging onto a build you grabbed off of mobafire or something.
Hopefully that helps a bit, sorry that the thought process is a little jumbled.
