can i just ask, what do you want them to do, they can't just do more and more rounds, these events are expensive we aren't paying for them and we should be happy for the ones that we get and can't expect more events, so the only real thing is a quiz, but its hard to make a quiz that 128 people will pass, i really see no way around it, i know it sucks but yeah what do you want them to do?
Well, they could do any number of things. They could keep the random selection process of picking people, and increase the number of participants allowed in. Making the maximum number of players allowed in 256 would help a lot, despite adding just 1 more round of single elimination. Raising the number to 512 would quadruple the number of players allowed to play in the tournament compared to this year, and would only require two extra rounds of single elimination. It would be optimal, in my opinion, if there was no limit to the number of people accepted, and Swiss format was used in the preliminary rounds as opposed to the single elimination format used this year.
TPCI could also require online registration, like in the 2008 Showdown and at JAA. This would allow the predetermined number of participants a guaranteed spot in the tournament, and it would also give an opportunity to those who lived close to the tournament location but were not selected to come and be picked as a replacement for someone who did not show up (of which there would likely be many). This has worked in the past, and there was generally far less complaint about this process of selecting competitors compared to this year's process.
You say "we can't expect more events", but that just shows how little you know. The JAA tournament had 26 regional locations, which is more than 4 times the number of regionals in this year's tournament. When you consider that Pokemon's popularity has risen greatly in the 3 years separating the two tournaments, where is the logic in having less regionals? While these events certainly cost a lot of money for TPCI, a lot of money is being put into traveling to these events as well. This waste of dollars is not necessary, and could be easily remedied by increasing the number of regionals. You are right, we should be happy that these events are being held in the first place, and I certainly am, but I am also very disappointed that these events are not being held in the best way possible.
I realize that both you and I have extremely biased opinions, as you were lucky enough to not only live extremely close to a regional, but also to be selected in the random pool, while I endured a lengthy trip to get to the nearest regional and was unfortunately not selected in the random draw. However, I think that the majority of the people who went to this year's tournament would agree with me. When the vast majority of people going to a competition are not even allowed to play, what does that say about the competition itself? What do I want TPCI to do, you ask? I want them to hold these tournaments in the best way possible, because with some fine-tuning, the VGC could become very successful and long lasting.
