You want honest criticism? I liked the video, it was fun to see quick action. But that's all it was: Action.
Skill-wise(and not only yours), not much was standing out besides your obviously awesome and overpowered build. Mainly it was not your skill that allowed you to score so many kills but rather the lack of it from people on the receiving end. Many times people would drop their blocks when they easily could have blocked you. I think it's mainly that when they get hit by you, they lose about 80%-90% hp and are demoralized, thus resort to reckless actions.
But I'll give you one thing: You're good at slipping away from ganks relatively unharmed. And considering everything above, good at taking advantage of people's mistakes.
So all it takes for average NA skill is to increase. I think NA top players are pretty equal to EU top players but not the average skill level, EU wins in that aspect.
