Also, we were right weren't we?
Yes, you made a guess, which happened to be correct. It was a guess 90%+ of people, myself included, would have made. But that doesn't matter because there
was a possibility of us all being wrong. Tomatoman could have proved us all wrong and won the event all by himself.
The free replacement thing was only for teams who had players who never even showed up. Penalizing teams for that would have been kind of unfair, especially if the players in question cost a lot of cards. Your leaver
did show up, even though only briefly, and didn't give any indication of having quit. He wasn't offline long enough to get a label of being "missing", therefore replacing him for free was not an option.
It's the same situation is someone from any other team now disappears: there will be no free replacements after teams have been confirmed and the event has started.
