It appears that DA 2 may be a dumbed down version of DAO,like ME 2 was a dumbed down version of ME...Shorter,more action orientated,less loot,fewer options,streamlined,and even more linear than the first.Catering to the casual audience is ruining gaming as a whole.
A mandatory install could have allowed the missing graphical effects present in the 360 version.
It was ported from PC vs being coded specifically to take advantage of PS4's hardware...that's what happened.
