It depends on what your aim in the action scene is. If it's about how badass certain characters are then you'd want to focus on their exploits. If it's about a mad scramble for escape you'd emphasize confusion and fear and movement. If it's a giant battle then all kinds of things can be written about, depending on whether you're describing carnage at eye-level, or talking tactics from above.

From what I've read recently, the Malazan book of the Fallen series featured fights and battles of many sizes that were described fairly clearly and capably while also being entertaining. It's a fantasy setting, though, so take that into account.

I think the key word you're looking for there is 'subject' and 'theme'. Action scenes need to fixate and pander to the subject of the action you want (be it a character, behavior, fighting style) and the themes like fear and the like.
