He knows perfectly well what you were responding to and his reply of rankings mean jack shit is still perfectly valid, it doesn't take a genius to work that out really does it....
Pro tip for any further posts you may make, spouting off "I'm in a xx ranking guild blah blah etc" does 3 things for you:
1. Make you look immature and insecure in your knowlegde and makes any point you are about to make worth far less than if you'd made the point only.
2. Proves absolutely nothing and does not back up or substantiate any point your trying to make
3. Rather than impress anyone it reduces your credibility of anything you say from then onwards on the subject.
In other words, there's better ways to approach a subject with which you wish to make a point about.
