I still haven't uninstalled it, but I know from watching reviews and streams that there is very little worth actually playing in the mid-game to end-game.
Agree that a DLC by itself won't set things right like it did for DD1's DLC. It needs an overhaul. Feels like this was slapped together in a short production cycle and rammed out the door by Capcom. Nothing about DD2 says "we worked on this game" it feels designed by a team that showed up to work late and hungover with project leads not checking anything as long as it makes the project deadline.
