Members I know some Legacy 1 fans who this happened to and they haven't been back since, they've also dropped their cc membership. Year 1 of Sitake was great with Ty and all the hype but BYU chased the current demand/money and turned their back on long term fans who would have kept renewing their seats if given the opportunity.
They really should follow the model that the Jazz use and allow people to renew their same seats every year, if you want to increase the seat prices and people choose not to renew that's fine but their online seat selection system isn't great. I've talked to Legacy members who have let their selection time lapse and watched the same seats they were looking at stay open for over a month as other tiers could select leading them to believe their membership really didn't help them get better seats.
