I guess I don't think the Value or Moderates are overpriced when you look at all the benefits.
Free parking at the hotel, free internet, transportation to the parks, package delivery, complimentary airport transportation. Charging back to the room, a dining plan which enables you to do a lot of pre-payment of meals, satellite TV...
When you get to the Deluxes, you have very nice amenities and that's where things get costly with room rates. Disney really needs to plus things up for Deluxe amenities which I think will eventually come.
I do Values and Mods, mostly Mods. But if I just went once a year then I'd probably do a Deluxe.
My prediction is that FP+ is going to change things a lot at Disney, and the benefits of being on property are going to be seriously worth it especially during busier time periods.
