When someone tries to tell me Tristana mid isn't good

You know tristana is the greatest midlaner, the very greatest midlane, I spoke to a guy the other day who was a midlaner so he knew a lot about the industry, he told me, 'Requiem Tristana is an amazing laner, so incredible.' I look at him and go ', Is she?' I asked. This guy was a great guy a very stand up guy who was very intelligent, so very smart. He showed me pentakills left and right with tristana midlane and really showed me she's the greatest midlane ever and I looked him in the eye told him, I was very sorry I ever doubted him. That is why you should pick tristana midlane.
