The only mechanics that have changed are the way the healers act. If you're melee rushing then this is irrelevant. In regards to the animation changes: If jad stomps his two front feet, the he is using the ranged attack. If he stomps his right foot, then kneels (with a fire ball on his back) he is using magic. Melee has no long animation, so if you intend to protect melee, do so immediately after the other attacks hit. If the prayer part seems confusing, find a video on youtube.
