There is actually a list put up by someone earlier in this thread that I actually agree with completely. And here it is below

Kinect/Move controls
Facebook/Twitter integration
Microtransactions
Day One DLC
Origin exclusive
No tactical camera
Dialogue wheel with worthless paraphrases
Multiplayer that sucks resources away from single player
No mod support
Making combat more real time, thereby further marginalizing full party tactical control
Not beefing up the graphics on a technical level
Mage/Templar War with one note cardboard cutouts like Orsino and Meredith
Rushing the game out
Not including some kind of narrative dénouement
Import bugs
Pointless cameos and/or bugged cameos
Uncanny Valley plastic faces like DA2
Recycled dungeons/maps
and probably more...
Now the Day one DLC I wouldn't mind if it was included in the normal Game, as the way that I see it, instead of saying making it a DLC if you are able to have it on day one, then just actually put it into the game and avoid the whole "Oh hey look at this! Day one DLC! Give us your money!" type thing.
I'd say having our choices mean nothing would be the one thing that would prevent from purchasing the next game in the franchise, if that is the case then why even play the first games and DLC? If it is just going to be railroaded and made canon regardless?
I wouldn't mind if they took the extra time to just make it to where our choices actually mattered. I've seen mentioned the OGB And Morrigan and either doing or not doing the DR (either don't have the child show up or at least not an OGB since in the epilogue if you romanced morrigan that she was with child. Of course that would be if you didn't accept the DR)
Zevran some how being alive/still being Zevran in his flirty ways in DA2 even if you killed or romanced him. Leliana being there on several occasions in DA2 even if you romanced her in DA: O, I can understand that some of that may have been during the time of awakening, GoA, and WH, but something just doesn't sit well.
Mostly having the proper reactions to what your Warden and Champion did through the imports, if your warden and/or your Champion was kind of a D*ck or B*itch then the peoples reactions should be kind of mixed in my honest opinion, not this constant "Oh my it's the Warden/Champion that some how saved the day!" Throw in some people who just don't flat out like them or something like the one guy in the crowd that goes "Boo! *hiss*" just something more of a reaction to what my character is doing in the world then just everyone being a little sheep because I just happened to put a weapon through someones head. But of course the is just me.
