I don't personally like the changes PUI has made to the game this year either, but the only real thing we can do is make PUI know that we don't like it and then try to have fun and not lose interest in the game for a year.
Personally, I am looking forward to getting to Nationals and seeing what changes PUI has made to it. At the very beginning of the season I was let down about the World changes but I was happy to hear about how Nationals was planning on being a bigger event. For those that didn't really have a chance to get to Worlds last year, Nationals was their own little Worlds, and I truely can't wait for Nationals this coming year.
Part of me feels the current changes will really push players to realize why they play the game. If they play the game to get to Worlds, then they might reconsider playing the game, which is bad for the game. Either way, if someone plays the game primarily to get to Worlds, they most likely would quit sooner or later anyways once they don't get to Worlds one year.
You will have to play to have fun this year unless your one of the few that can get to Worlds via cash or trip.
