Did you get it in the mail (haven't checked today)?
It seems as though Universal wants to see when and during what events we are most inclined to visit. As we all know, the off-seasons are a big impulse and so are the free events in the parks, but perhaps not that many passholders go then, so maybe Universal wants to give more incentives to visit. Well, all based off of working around what you said, haha.
Basically, I doubt we're losing anything (perhaps even gaining something) if we're anything above Power status.
