he is arguing about whether or not games should be balanced for competitive or public play
He's saying that games should be balanced for competitive play because a lot of what pubs think is overpowered is simply them not knowing what the hell it is.
I think that making a game not fun until you're good at it is always a terrible design choice, and I think that zircon agrees, as he goes on to say that the balance fixes should not be nerfs or buffs, but instead things that make it easier to get good at the game without having to play it for a million billion hours.
