Only six players for Origins? That's a bit surprising honestly. I had thought this game was pretty popular, but six players is a very low turnout, even for a game of this type.
Not to detract from anyone's victories, but these tournament results really don't tell us much about the meta either. Six players with no Wizards, Forcemaster's, or Priest/Priestess's just doesn't tell us much about the relative power levels of the various mages.
Also, an all core book winning is very odd to me too. It makes it seem as if the expansions haven't changed the meta at all, and we're still sitting at square one. It seems obvious that the expansions have indeed changed the meta, which is why results of this nature are very, very strange.
I just don't know what to make of these results honestly.
