Yeah, size is the issue. I live in the northern central part of the U.S., and was willing to drive to it in Toronto, which is still 10+ hours away. Flying to Vancouver? Not worth the cost, esp. considering it's at an anime con (see: I'm married, and don't need the temptation).
Once again, the prize of getting Nationals is just icing for the distributors, instead of a treat for the fans. This is really the worst abuse of it. At least at Gencon and in the UK, they generally have space for most who want to play.
I think it's cool they're rewarding the west coast, as a different group of players get to experience it. However, it's a poor Nationals. At least Gencon gives attendees something else they'd want to experience, for the most part. Not sure most ANR players cross heavily into the section of the Venn diagram that would attend an anime con.
