I have a few comments to Wyll's questline.

Firstly a bug in the Blighted Village when you need to knock out Fezzerk. If you get him to low enough hitpoints without killing him, he will beg for mercy and Wyll can ask his questions. After he has done so, Wyll asks you to kill the goblin, which you can choose to do. After this Wyll will however be mad at you for killing Fezzerk, because he needed to question him. There are som continuity errors here it seems.

Also I think it would be nice to get some indication earlier on that Wyll is looking for someone. One does not need to get all the details, but it might make one bring Wyll to the Goblin Camp, instead of an optimized party.
