Here's where this is a problem: League leaders / Stores will take a decent hit on PreRelease attendance and may not continue PreReleases if you can just pick up the stuff on day of. They should've delayed these a very large amount after each PreRelease season.
I run PreReleases and this could be kinda devastating to my league. No more PTOs, League Challenges are a joke, League Cups becoming more and more toxic, and now this? Whats left for a person who wants to run event to get out of it other than generic satisfaction?
The less a leader or store is incentivized to make money, the less Pokemon events there will be. Have fun with mini events at home I guess though. -_-
