Haunt Sanctified Power work logic

Now: all Haunted enemies within 50 yards are pulled to the Witch Doctor, AFTER i stop casting HAUNT. In the Jade Harvester set, it is impossible not to use the profile skill for 5 seconds, and in other builds it takes too long to scatter the Haunt skill.
Maybe: replace Haunt > Locust Swarm. or pull enemy every 5 second(without stop cast Haunt).
