its not a spoiler...but it might somewhat spoil what you put under a spoiler? so...
Yeah, I suppose it doesn't need spoiler tags, since it doesn't spoil anything.
Replaying Awakening last night and the quest where we first meet Justice, made me think that what DA2 really needed was for us to see more of Justice actively controlling Anders for brief periods like in "Night Terrors".
Having Justice sporadically take over and interact with the various members of the party, would have allowed us to get to know the character better, instead of us always hearing about him second hand from Anders. "Show, don't tell" is always a good tool and seeing Justice become more corrupt and seeing the effect that had on Anders as well, would have made the ending far much more powerful and tragic for both of them.
Instead, I always felt it was Justice that was the more responsible of the two for the destruction of the Chantry and that by Act 3 we were definitely watching the triumph of Mr Hyde over Dr Jekyll.
