Hey guys, just caught up but is it too late to talk about Cole?
Whatever, I'm a going to add my two cents...
I chose to make Cole human, though I did not make it lightly. Seriously I had to take almost a full day to decide and even then I'm not sure if it was right. But my reasoning was that Cole greatest fear was that he would hurt people again. Like he did when he first came through the Veil. Even before the mission he makes you promise that you will kill him if he goes down that road again(and if you don't you get a massive disapproval hit).
So with that in mind, I chose to make him human. Because then he will retain the lessons he has fought so dearly for. We are given no assurances that spirit-Cole won't revert back to mercy-killing and misunderstanding situations and pain. I feel like Cole (as we meet him and before the change) would not want that.
Of course I understand the spirit choice as well and I can't help feeling that is actually the "right" one. I don't need Cole to be human to relate to him. I just don't want him to lose himself again and force us to make good on that promise. Spirits in the living world do not have an excellent track record of staying true to their purpose and Solas is going bamf out and not help him stay pure.
I don't think there's an objectively "right" choice. I do think Cole is less unhappy if he is made a spirit, but then again I think it's a bit odd to ascribe "happiness" to a spirit. A spirit of Compassion doesn't really understand happy or unhappy - it's more "this is right" and "this is wrong". Making him a spirit is putting him into a more pure and uncomplicated form. It's a familiar form to him, and so he finds it easier to do what he loves: help people. But he's also blinded to the nuances of human behavior, and his helping is limited.
If he becomes more human, his life is much more painful. He remembers, and people remember him. He cannot help using the techniques he could use before. But he has a better understanding of people - I think he mentions understanding Cullen better - and though it's more difficult to help, he's able to help in new ways. I think he's better able to understand and confront the big/deep problems because he can actually empathize with people.
TL;DR I think they're roughly equal depending on how you're looking at it.
It's probably going to be a while before we get any DLC..but I hope they at least fix the Solas quest glitches and bugs soon!! I keep hearing that there was supposed to be another quest for him that isn't working.
I think we'll get an announcement about story DLC in late January or early Feb. Hopefully get a new patch (where is my patch for XB1?!) in early January...? That would fit the normal timeline. They do seem to be having a bit more trouble with patches, or maybe it's just the holidays.
