I don't think the new crafting system is that good, but it's maybe promising (it feels very incomplete).

I haven't really felt any change in the main storyline. The end is different, and combat-wise it's better, but storywise it's still meh (personal opinion). I like very much the little stories between each region (cyseal invasions, hiberheim elemental war, luculla miners, hunter egde infiltration, dark forest is less interesting but its end game so ok), but the overarching story I really dislike (The Source Hunter thing and the Astarte thing, Xixxaxx, everything in the Homestead but the little goblins you save which are hilarious, all the little animated movies).

The new headless Nick is really cool, and the subplot aswell, I agree.

The voice acting is good, no complaint. I think one change that could be made is pausing the voice while in trade/shop window (Cyseal merchants hurt the ear long term). The same way the voice acting is cut when you press "next" "next" "next".

Tactician mode is cool, perfectible due to balance problems, but a very good step.

I think the two big plus things are the new voice acting and the tactician mode for me.
