Shadowmeld is so ridiculously overpowered now it%26#39;s fantastic. Pull too many mobs and about to die? Shadowmeld. Want to run to a quest giver but not fight all the mobs on the way? Just charge in, Shadowmeld, and they disappear. Want to resurrect someone in combat and Rebirth is down? Shadowmeld and Revive.
Shadowmeld is particularly awesome in combination with instant cast Flight Form. In any situation outside you can immediately get away: Shadowmeld, then pop into crow form and fly straight up. This works even if the mob is right on top of you because of the instant cast; being pulled into combat doesn%26#39;t interrupt you like a normal mount. About the only thing you can%26#39;t do is get out of combat while falling; Shadowmeld doesn%26#39;t work when moving.
