How good is this item in actual fact?

The 16 second cast time seems like it makes it fairly limited in use at first glance. But seeing as there are many situations where a charm break necessitates mezzing all mobs in play you would - in theory - have enough time to click the stick and never have to spend mana on charming (up to lvl 49 stuff).
