ok, it seems that most of the priests didn't know how to use LoF correctly, so here is it.

1. join a raid or heroic, for example, Blackrock Caverns.

2. select a victim from your group members.

3. clear trash till the 1st boss.

4. during boss fight, when the guy try to run away from the boss, pull him back with LoF, then Dispersion & run away.

5. blame the poor guy for not knowing the fight & die.

6. keep clearing trush till 2nd boss.

7. during boss fight, LoF away the guy while he's blocking the beam, and wipe the group.

8. defame the guy for noobing, vote to kick.

Good! u've done a great job!  , now, get a new target & repeat step 2-8. if u can't do it properly, u r not a qualified priest.
Remember, a good priest should always do 2 things:

1. throw some1 off cliff,

2. sabotage ur group.
