However, this dual-wielding system is unique. RuneScape is giving dual-wielding abilities to more than just those who prefer blades by making it available to magic users and ranged combatants as well. Players can dual-wield magic, ranged, melee, or mix and match any combination.
Another less dramatic change includes improved weapon stances, which add a casual stance to sheathed and attack positions. The stances also are individualized for different weapons. Finally, the devs have upgraded avatar models to include actual fingers.
To see a demonstration of these changes, you can watch the video. And for even more details about The Evolution of Combat, check out Massively's interview with Lead Designer Mark Ogilvie.
