There was notification, just not on AGN. Also, the grand prix event, which is constituted by regular shooters, took up half the shots. They earned their pre-qualification by competing towards EBR at the grand prix. I do believe AoA will be changing it a bit next year but
@AOA ROB or
@Centercut would be able to speak to those potential changes better. From my understanding, it looks like there will be more "regular" shooters than ever before because of that grand prix, and certainly as diverse as ever and much more so than others. As for it only being Pros and YouTubers, yes Pros do make a point to shoot the Pro division, it is their hobby after all. As for YouTubers, I don't think any serious YouTuber is competing, but I could be wrong.
Ultimately there is high demand and limited spots so some will not get in. Hope that answers your post more thoroughly.
