Romans 15:4 "For all things written aforetime for our instruction, that through our endurance and COMFORT from the scriptures we might have hope." If you take a superficial viewpoint of Job, yeah it's depressing and using the account may come across as nonsensical. But it's similar to the Psalms...or a Victorian novel. Through the adversity and perseverance of others, we teach ourselves how to cope and handle trying situations. EVERY situation does not call for professional help, therefore it shouldnt be expected that they suggest that this be mentioned in such a case. But, as spiritual overseers, it is their responsibility (primarily) to be of any spiritual assistance they can to the congregation.
Obviously the elders can use their discernment and recommend professional help. The WTS doesnt have to tell them every little common sense thing to do. I think the point of the video was illustrating how elders can use the Bible inffectively and perhaps pour salt on an open wound.
Isn't it interesting that the elders are so heavily criticized for trying to do what they are SUPPOSED to do (according to the Bible). Nevermind the fact that they do this WILLINGLY and without pay, unlike 90%of religious leaders today.
