Sorry, but "LOS" as a dev's excuse is nonsense. As a healer, I can stand right in front of a target, having the crosshair centered on it, but still a full heavy attack with the healing ward often does not trigger. Instead the healing ward shakes like mad. You can then try for 3, 4, 5 times, it just does not work. I then have to use any skill to break the error condition, but that requires magicka - that you wanted to get from the heavy attack... It really sucks how ZOS forces people into a playstyle of heavy attacks when these attacks often do not work at all. And it is getting worse over the months...This can even happen without LOS, although that is the main cause.
