Well I couldn’t get a ticket in 17 but got one in 19 and 20 and I live in Qld but am currently at 22 years, so did I deserve a ticket in 19 ?I think it depends. The example you gave is fair enough, but should a 20 year member who has contributed the bare min GA membership and hasn't been to games, really get priority over someone who has maybe been an 8-9 year member but has contributed through reserved seating / various apparel items etc.
Whilst I get your point on loyalty, I don't think its the only thing that matters. Its the overall contribution to the club that should matter.
Eg. in my personal circumstance (and I've been happy not getting a ticket to the GF's in 2017 and 2019) as I understand I haven't been here for the suffering that many have gone through, but I've had a reserved seat membership for 7 years now and went to watch games in the previous 2-3 years, but have only been in Australia for 11 years (and had never seen a game before I moved here). Theres not much more I could have done than what I have done, yet there are people that have been 20 year members, base membership only, don't go to games that always get priority.
Loyalty is shown in more ways than just length of membership.
