Idk if thats cata bullshit but you can cleary see in http://warcraftmovies.com/movieview.php?id=155295 that 1. Channeled spells will still fire their missiles even though target runs LoS and if you check @ 15:42 when the priest starts mana burning and the mage runs LoS the cast continues. LoS is only checked at start & end of cast.
