The reason why you lose.
It's because people don't know how to build to play against that champion. No matter where you go as a solo laner, you need to adjust. DOn't just keep building xbuild because its strong late game, If you feed then all that time was wasted for nothing and you're making it harder to carry you. Seriously people, adjust to what your playing against and not what's going to be strong late game cause if you feed, it's all pointless.
