So I just finished Witch Hunt, and overall I must say it wasn't bad. Pretty much what I expected to an extent, and overall I don't feel like I was ripped off.
The companions, Ariane and Finn, were actually great and I liked their particular personality quirks. Party banter was entertaining, too.
Dog was an amazing companion to have back, and the new codex entry dealing with his status after Origins was honestly one of the funniest and best things I read
Also, you'll see another familiar and favorite face in the game, though I felt that the voice sounded kinda wierd-sounding. New voice actor for the role? I don't know.
The feeling of searching for Morrigan, be her friend or lover, was definitely there despite the brevity of this DLC. I liked the way the ring was implemented in the game. Overall the DLC takes whether you romanced her or not, and based on the dialogue choices it provides, really lets you express how your Warden feels about the search. A quick but otherwise cool personal touch that I was hoping for.
One odd thing (not sure if this is bad for others but it was kinda bad for me), was the extremely high-level equipment your party has that leaves almost everything you saved for them from Origins or other DLC/Awakening obsolete. Thankfully because my warden was a warrior this playthrough I couldn't access any chests and therefore wouldn't get an overload in loot.
Before I go into my one complaint, I must say that the confrontation with Morrigan (romance/DR-wise) was what I expected and I'm fine with her not revealing anything specific.
Now, here is my one complaint about the DLC:
I unfortunately got the Dark Ritual bug as well. I honestly don't know what factors or patterns lead to it, but I reloaded a point in the game each time to try out different dialogue choices, as I was thinking maybe it was choice-based rather than straight import how the game would recognize whether one did the Ritual or not. Sadly I realized after a couple of reloads that it was a bug...
I saw the ending from the youtube clip provided and that is what I base my reflection on this DLC on, and overall I think it revealed just enough without giving away the entire thing and I'm happy with that.
If the bug gets fixed, or I have time to replay or even redo THIS particular Warden, then I will probably enjoy this DLC more over time. I think now I just have to let everything sink in.
