Actually both of those lines of reasoning are perfectly valid. We're talking about one pokemon breaking a metagame. You need to look at the most basic definition of "broken", which is when it becomes reasonable to expect that any given battle will focus on one pokemon. When something sees record usage DESPITE their flaws, that is when something is breaking the metagame. If Physical attackers are prominent in the metagame, then there's no way something destroyed by physical attackers could break it when it drops down. The last bit of your post with the calcuations is great reasoning, but the first half is completely off base. When you start showing how it's main weakness is not that big of a weakness (with the damage calcs), that is when you can start making a claim of brokenness.
I don't really even disagree with what you posted, I just think it's funny when council members are saying that they will vote to ban things before they even play a single match in the new metagame. THAT'S missing the point.
