Discounts only get offered if they haven't hit certain targeted levels for occupancy. So standard rooms at a deluxe may very well fill up faster than a more expensive class, so no discount gets offered. You can always check here ->
http://www.mousesavers.com/historical-information-on-walt-disney-world-resort-discounts/ to see if there is a likelihood of a second round of discounts being offered, but usually if they didn't discount it the first time, it won't change the second time. Remember that in more recent years/discounts, there have been more and more dates excluded, rooms types/resorts excluded, and in some cases even varying discounts within a resort for the same day. The discounts are becoming much more targeted to fill empty rooms.
