Maybe you didn't understand that him comparing his aim to the players in NiP in 2013 was irrelevant to his main point, which is that the pro scene was garbage at the start of CS:GO, which isn't referring to the level of aim, but rather the level of tactical depth at the top level. So in retrospect, your reply regarding his aim is actually irrelevant to his main point, and only highlighting his side comment.
An example of this just in case you don't understand :) =
Person 1: Hey, FaZe are looking a lot better with coldzera than recently but they were still miles ahead with karrigaN - They should really look into getting a proper IGL so NiKo can frag out. It's such a shame to let a talent like him be burdened by the role of IGL, I really hope this FaZe lineup can prosper though. I'm as tall as NiKo btw!
You: How do you know how tall NiKo is now? Have you measured yourself recently? You're probably using outdated information, big difference.
That's you mate, you reply to the unnecessary information that isn't relevant, get a grip on reality.
