Am I the only one that is too dumb to understand this? Or is it just confusing 
I believe what he means is that the really really good guys need us lesser skilled guys to fight and beat andto keep them interested. That's how I read it anyway. If they only had straight noobs to pick on, well that just couldn't keep their interest or skill level up, but guys like us can give them enough of a fight to keep them sharp and wanting more, without really putting them in serious danger of losing. That's how I read it.
I feel good about that, because I feel like that post right there elevates me to the middle skill level tier from the bottom ones! Hehe.
