Ya, the GoD version of DAO is not worth it if you do not already own all of the DLC for.
It does not include Stone Prisoner (not part of the sale, and is included with all retail copies for free) or Blood Dragon Armor (not sold separately for the console versions).
About the above suggestion, note that while that will work for the DAO DLC, the UE does not add the Blood Dragon Armor entitlement to your BSN account, meaning it will not unlock in DA2 or ME2 (the UE comes with a code for ME2 that will add the entitlement to your account, unlocking it for DA2 as well, but renting it will most likely mean that the code will not be included, or that it will have already been used).
