oriannas farming ability is too strong

Oriannas farm is way too good, an average player on her can get 200 cs 20 minutes in. That same player wouldnt be able to get that much cs on ANY other champion, you'd have to be a god to do it. But not on orianna, shits rigged too easy to get fed from farming as her. 200 cs at 20 minutes is huge, and i see it on every orianna. Getting that much farm is a huge advantage in this game, its a lot better then you would think. I'm not posting this because an orianna had double my cs and i'm raging, i like to think im a pretty good player and usually have cs leads on my enemy lane. but i cant do it against an average orianna, they always have at least 20 more cs then me at 17 minutes or so. Then as the game goes on, when i get to 200 they have 260. Her farm only gets farther from everyone in the game as it goes on. This may seem somewhat fair and not that big of a problem, I can see Riot reading this if they read it and just ignore it, but it's a bigger problem then it seems. Farming in this game is a big part of it, and for her to be so good at it creates an unfair advantage for her team.
