I don't know the exact camera angle, but D:OS does pretty much have an isometric view. There is a video of the E3 presentation in the
Gamespot article.
For DKS, since you got to the battle tower, you could unlearn your skills at the trainer and go for a build that utilizes a less frantic combat style (and/or reduce the difficulty level). An archer shouldn't need to do much frantic button mashing, or much running around after learning Splitting Arrows and Explosive Arrows (Stun Arrows and Poison Arrows help early in the game). Some people keep their character mostly out of direct combat, and let their creature, a summon and maybe a charmed opponent handle most of the fighting.
