yeah I agree.
I only started playing mp a few weeks ago and while I'm not quite tired of it yet, I am getting twitchy for all the games I've put off since DA:I's release. I've got a few autumn ps4 releases I had planned to be playing around about now and my steam wishlist & unplayed list is always getting bigger.
a dlc soon (like within the next month) would mean that when I inevitably go to those games a bit, I'll come back to damp instead of forgetting about it and moving on to the next new game. I know myself well enough that I don't usually come back to a game for a dlc if it's been a while, no matter how great the dlc is
can be as little as new maps or a new faction type. I only played a little bit of "vanilla" mp because I didn't know you had to separately install the dlc, but destruction didn't really add enough to qualify as something new. If I had played MP from launch I'd definitely be bored by now.
