It isn't rarely used if you have a party of druids. A druid can cast this spell many times a day at high levels, and allows a sole NPC to control a combat.
Most abilities of druids need to be combined. Wildshape is near useless in combat at higher levels, unless you use greater magic fang. Likewise animal companions. I guess it is just a different style of play to go druid.
