Magic Kingdom has a ton of attractions (that are great in my opinion) that never have a line though. CBJ, Tiki Room, Philharmagic, TSI, HOP, people mover, COP, the stage shows, the parades, HEA, etc. With even the slightest bit of planning I am confident that your average DAS user could spend the entire day occupied doing something in between return times without the benefit of the 2 additional pre-selects, and also still have a much better day than even the best Genie+ poweruser. The preselects are just completely unnecessary in my opinion.
