I didn't end up competing in VGC this year since I made TCG top cut and leant my DS and cartridge to a junior friend. So I can't say my perspective comes from someone who experienced VGC as a player, but I was there the whole time.
Location: BC regionals location was awesome. Surrey is a bit sketchier of an area of town than most places but the actual location itself was great. We had enough room, the atmosphere in the tournament was good, there was food available for people between rounds, the room was nicely lit and vibrant, and of course it was close enough to the hosting games shop that they also got a small bit of flow afterward which was nice to see.
Timing: I'm pretty sure in VGC all divisions played at the same time. Our regionals was smaller than most (it's the first time Canada's had it's own regionals!). Nonetheless, the attendance was encouraging and hopefully we continue to grow. Next year if they implement more events (states/cities/BR?) that would be very beneficial for encouraging the Canadian community.
Other Comments: We also got a lot of people from Seattle considering they lost their VGC location last year. Given that you can't win the first place travel award outside of your own country, but can win the stipends, I felt this was overall ok. In masters, there wasn't a contreversy about this anyways since a Canadian took 1st. But in Juniors, the 1st placer was an American resident whose mother had Canadian citizenship, and 2nd place was an American, so the 1st place prize ended up being passed down to 3rd place (which happened to be my junior friend who I leant my team to). I don't think the system needs to be improved here, since it doesn't make sense for Canadians to win flights and hotel to US nationals (they're Canadian...) and vice versa. I also think that with Canada only having 2 regionals, it would be a tad unfair to allow Americans to come up and nab flights to their own nationals in Canada. If we want our community to grow and flourish, we can't afford to have people take our prizes.
As such, I'd say better advertising of the specifics of the travel awards next year would ease the tension on this issue. Instead of putting it in fine print (and I'd add the wording was ambiguous when it was first released), it would be better to make this a more up-front issue.
The screens I can see being nice for Top Cut, but I don't agree with them being on during the regular tournament. We forget that last year it was single elim, so if you lost there was no advantage to be gained from watching others' battles. If they do bring back screens, I think it would be great! But only for top cut, and ensure that finalists can't watch other battles.
I'd also agree with the sentiments that some background music would be nice for both TCG and VGC. At my pokemon league, we often have pokemon route music or battle music playing as background ambiance. It just helps the room not feel dead when everyone is in the zone and focused on their matches. Of course, Eye of the Tiger and Final Countdown are necessary for Top Cut :P And if I could recommend a 3rd song to add as a staple. "The Touch" by Stan Bush. Aw yeah.... (seriously, it's just inspirational).
As for the format itself, Top Cut is necessary. But I would add that even just having Swiss is so very appreciated over last year's format. Considering you always had to go X-0 to win the tournament, Swiss just makes it so you can lose in rounds 1-6,7,8 etc... and still come back for a top 4 finish. Major improvement here and highly appreciated by the community.
As a final note, the regionals should really be spaced out over at least 2 weeks. It would help immensely in supporting attendance at individual events (probably raising attendance at each event by potentially 1.2-1.4x considering the potential overlap of attendees).
Finally, and this deserves big bold letters:
CHANGE THE DATE! REGIONALS SHOULD BE AT THE END OF APRIL AT THE EARLIEST.
I know that many of my friends couldn't make it because of final exams in university. Considering the core of the masters attendance comes from the university-age group, it's ridiculous to hold regionals amidst final exams. I was lucky that my I had a long enough break between exams that I was able to attend.
