I too am not feeling the "wow" factor that I should be feeling. Not due to the trailer, mind you. I think the trailer looks awesome, and I'm really hoping we get some well-deserved answers. While I don't want everything spelled out for me, I would like a little bit more clarity, and it seems the DLC is aiming for that.
However, Dark Souls III just felt...lesser than every game before it. And yes, I'm including II because I like II. It wasn't a bad game by any means, but the magic, that feeling of wonder and vastness that all the other games have had just didn't strike me with the third one. And when the first DLC came out, I was hoping for it to fix this, but it really didn't. It was just sort of...there. I like the implications of it, but I get the feeling they would have done better if they did what they did with Bloodborne: combine the DLC into one piece and release it all at once.
Also--and I'm sure people will be upset with me over this--the fact that there are no trophies for the DLC was just icing on the "Meh" cake for me. I still haven't actually finished Ashes. I'm at the final boss, but I just have no desire to keep playing. Hoping that when my friend gets there, the spark will come back.
