If you don't already know, the big bullet-point when it comes to Age of Conan: Hyborian Adventures is its "Real Combat" mechanics, Funcom's stab at "combat 2.0" for MMO titles. It involves a combination of looking for a visual indication on an enemy, noting whether he is weak in one of three areas, and then hitting the applicable hotkey to trigger an attack.
This extra complication certainly adds a little more action to standard sword-swinging, with players having to position themselves in addition to mashing the right buttons, perhaps on par with playing a Rogue in Warcraft. However, in the end, it didn't feel like a giant leap forward in MMO combat. This is not so much revolutionary as it is evolutionary.
