Call of the Hunter is not yet implemented.
Bullseye is the final golden dragon and therefore can't be unlocked yet.
Windburst, however, is a powered up ability that swirls some airy ground effects around you while charging then expels a burst of wind leaving a speed enhancer with visuals along the ground.
A lot of the animation for all classes is still in the works, so I don't think I'd go looking for animation videos to make a decision quite yet.
