When I was 18-25, there was no such thing. I had to miss games at that age because I didn't have enough points. I was ok with that. I'm also ok with an 18-25 category existing, but the point I made (which has not been addressed), is what to do if it is impractical to implement. If it's easy then it needs no further discussion, but that doesn't seem to be the case with UEFA administering all of the ticket sales. If you're 18 you are an adult. Being asked to adhere to the criteria like everyone else for reasons that may beyond the control of the club is not unreasonable.
