Have you been to a game in a while. There is NO WAITING LIST at all. I don't know where you get your facts from at all -- watching when the Leafs come into town or something.
I moved down to row 1 on 300 level three years ago because of so many cancellations. You can have your pick of seats now. It's not Florida but lots of choice.
Sabres were 20th in the league this year in attendance.

BTW, this is all with the border open. It' could be closed for next year.
The games are easily 20% Canadian fans most night and closer to 75% for Leafs and Habs. Other Canadian teams and original six like Bruins can be much higher than 20%.
Renewals this year are brutal. I put mine on hold for a year -- an option they allowed.
Sabres have major ticket issues now. The secondary market for tickets is US$6-40 for any ticket in house on a weekday. Season ticket holders have been disappearing because of this.
You don't know what you are talking about.
