When D:OS was first mentioned (as Project E) more than a year ago, the only detail we got was the top down camera view. I think it is too late to change now; there may be a year before release, but changing the camera would require changes to the UI, controls, level design, etc.
In DKS with my archer I found a mage head worked best with my creature. It didn't run off much that way, or draw many opponents into the fight who could have otherwise been left for later, and provided more of a shield than with a warrior head.
With a few levels into Splitting Arrows, it becomes a one hit kill for non-boss opponents at close range.
I usually don't bother with temporary boost spells in games (an occasional potion can help in tough fights), but at level 40 bought a bow with +5 Way of the Ranger, which I found very helpful, and put another 5 points into the skill right away, and maxed it later.
I stopped distributing stat points after level 15 (playing on nightmare) and found that up to level 9 of Life Line on most pieces of armour, plus any vitality or hit point bonuses on equipment, and a couple level 10 Healing Auras on jewellery gave me plenty of hit points. Level 1 of Healing came in handy, and there were few places I had to use more than an occasional healing potion.
