Well, it's kind of strange to seriously expect Red to pick Nosta. When banning as Blue, it's reasonable to leave it, but you shouldn't count on it.
SMKa, balance and skirm — I would definitely ban, then I banned Jebus Cross, I thought the opponent would ban LM as well, but he didn't ban it, and instead removed Diamond. After that, I had no choice for myself. For my preferences and the way the ban itself was conducted, everything was clear as day.
