This skill is only used in PvP against ball groups or big zergs but when you are in proxymiti of one of those the lag is so great that the 1 sec cast time become a 5 secs cast time.
So you just stay there stuck in place near a ball group trying to cast that thing and usually what happens when you stay still near a ball group is that you are dead.
Ball groups already benefits from some broken mechanicks (healing stacking, purge, ....) so they really don't need also to benefit from the lag that they help to create.
