The DL system works well if you're a morning person and have no problem getting to the parks first thing. On the other hand, if you like to relax and sleep late and get to the park later in the day you will find out that all the good FPs have gone. And the unpredictability of the FP times that will be available would wreak havoc on any ADR times reserved well in advance. With DL being largely a park for locals with many spur of the moment visitors, Maxpass works better there than the 30/60 day reservation system, but I would be surprised if WDW went in the same direction, especially since the 60 day window is such a powerful incentive for people to stay on property.
