Changes

::The combat model doesn't have a lot of depth in the previous games. It was very much a "one-skill spam" kind of game, which I think works great for the Normal [difficulty] playthrough. I think most of the audience is just fine with that, and through most of the Normal difficulty, it's going to be like that. But as you go into Nightmare and Hell difficulties, I think that the more serious player will appreciate a game that's a little deeper on the combat-mechanic side.

::Jay Wilson: Combat is as deep as the options the designers give themselves. Whenever you add a new capability to a monster -- potentially something that feels unbeatable -- it's more of an opportunity to expand the depth of your characters so they can respond to those threats. A good example would be if you look at Diablo 2: There were a couple of problems with just the power of the characters and the way they were made powerful. A player could run faster than any monster, so you could escape just about any threat. You had endless health and resource -- by resource, I mean mana -- because of potions. And you had the Town Portal, which could instantly get you out of any problem. Those were incredibly powerful mechanics to escape danger and were not class-specific. So every kind of class really had no need for anything like an escape skill or reactionary ability. They simply needed to attack, and if they ever got in over their heads, they simply ran away or drank potions. And it's the same response across the board.
