Just completed my first playthrough of the Demo, male mage.
Though the mage's staff attacks feel more melee than magical, I like it.
It felt how I wanted the Arcane Warrior to be, a combination of melee and magical combat. I loved that the staff animations had differences (minor, but there nonetheless) when in melee or at range, with Hawke actually striking his target with the staff.
The quicker pacing of combat allowed me to kite two of the Hurlock Grunts when fighting the Ogre, since I was the last person standing.
Winter's Grasp, Mind Blast & Fireball whilst kiting two Darkspawn and dodging the Ogre's charges and boulder throws... I. Loved. It. All!
No more were attacks a guaranteed hit when the attack commenced (for melee or the Ogre's boulder throw), and combat movement was much more viable for drawing opposition from a weakened party member.
Overall, the combat was more reminiscient of The Witcher. Which is, in my humble opinion, a damned good thing!
I've kept myself (quite successfully I might add) away from many of the spoilers about some returning characters from Origins/Awakening, and I'm happy I did.
I am truly impressed with the different look for Flemeth. Kate Mulgrew's voice acting, combined with Flemeth's new look, literally made me say aloud WOOOOOOOOW!
She's so much more sinister, and comes across far more as a truly machiavellian creature of awesome power and wisdom. At the same time though, leaving me with a sense that she may very well be a beacon of hope in the coming times.
I'm still riding a sort of "giddy school girl" kind of high at the moment, so I'll update this post when I've;
A) Calmed down some more.
and;

Played through as a Warrior and a Rogue. Which I'm very much looking forward to doing.
