Most of these replies are discussing whehter people preferred dao combat to da2, and what balance they'd like to see if those two styles were used as a template for da3. That's totally fine. Personally, I'm with those that'd like a return to a more tactical origins style of combat in many ways.
Encounter balance: fewer, more dangerous enemies per encounter again.
Rules of engagement the same for both sides.
Tactical positioning rewarded more
More grounded combat animations that make the combat feel more physical than flashy for flashy-sake.
One thing i liked from da2 combat was the ability to evade ogre charges etc. That was a serious improvement.
But there's more to consider here since there's a new engine that features the capacity for destructible environments. So i'd love to see da3 make use of that for combat. I think it would be cool to undermine pillars, trees, structures or walls and have them fall on enemies. Or to melt the surface of a frozen lake on which my foes are standing and see them sink under the wieght of their armor. Or to release lava from the confines of an old dwarven channel and scorch the enemy. In short, give us the aility to use the environment tactically for more than just higher elevations for archers, or chokepoints for warriors.
And of course, if we can do that then it's only fair give the enemy the same kind of ability too for ambushing etc.
