You can dodge and roll in combat, not just to avoid fireballs, though I don't know if you can attack at the same time, since I didn't take advantage of that option. You can jump and turn that into a melee attack, though.
On the Xbox version of D2:ED the left trigger performs a Target Lock so you stay focused on an opponent while you move around, etc, which zooms the camera to an almost over the shoulder view. I didn't use Target Lock much in human form, but it came in handy in certain situations in dragon form. I think the PC version has a Target Lock function, but it isn't assigned a hotkey by default.
Have you tried starting off combat with a bow, or something? Combat does get more interesting later in the game, as opponents get stronger and you start seeing more archers and mages, but after you choose an approach, etc, the actual mechanics of a melee warrior remain wait / run / Rush Attack to get close to an opponent, and then attack. You can mix up attacks a bit with Whirlwind, and later Thousand Strikes, etc, but it is still basically whacking an opponent repeatedly with something sharp and/or heavy (there is no combat micromanaging with blocking or timed attacks, etc).
About level 12, or so, you will be able to complete a quest that will give you access to a necromancer created creature. You can not control it directly, but it does offer options for a bit more strategy in combat (using it either as a distraction or shield).
