I'll have to disagree. As someone who hasn't let their subscription lapse for 10+ years without missing a day, who was a subscriber on the previous site version from Vertigo tour days, I think that the moment you let is lapse, you lose your seniority.
There really isn't a change for this tour compared to I+E and TJT tours. Anyone who was a paid member at a certain cut-off date was put in the first presale group; anyone who joined after - 2nd group. It was really similar to the current model even during 360 tour. Anyone who was a paid member at a certain cut-off date was in first presale group, and anyone who resubbed/joined after were put in newer groups. The only difference was that there were more groups for recent joiners/resubscribers... something like 3 or 4 groups in total: oldest members, people who joined after tour was announce, people who joined when tickets went on sale. So really, for the last several tours it been the same model.
What I would like them to have is more recognition to subscribers who are paying members tour or no tour, non stop. As an example, introduce another pre-sale tier for people, say, who have been subscribed since the last tour (and maybe include an extra ticket or two ;-) ). It would be a nice way for the band and management to show appreciation.
