By all means, play what you want. But the fact of the matter is that if I play a meta-build and I am good at it and you play a non-meta build and are also good at it, I will win. My point is not that meta is 'better'. My point is that I will beat each and every player not playing meta unless they are better than me. Hence why I see no reason to include non-meta builds in my calculations, as I don't have to worry about beating them.
