@yummylee: Yeah, that specialization was a blast to play too. I hope they bring it back. Also Mark Laidlaw confirmed on Twitter that he's a Rogue so mystery solved. I'm pretty sure I'm using Cole now, because a Rogue Mage sounds awesome. Now they just need to make some sort of Rogue Warrior and I'll be set.
If I had to guess I'd assume he'll resemble Fenris from DA2 a bit, who had those weird sorta-magicky abilities that were kinda incorporated into his unique skills, but he still fundamentally played like a Warrior. I doubt they'll give a Rogue actual magic spells.
Yeah that's what I was imagining too, but that would still be totally rad.
