Any point in enchanter debuffs?

Last night I had to use cripple in HoT because we only had one shammy so that helped alleviate mana. Some of the other debuffs like Lagarn's Lamentation wont work on certain mobs but have use in draining mana and stunning from a distance. Of course there is the powerful dispel line of spells but usally in a raid scenario, expect to only tash and give mind buffs to the casters and haste to the melees.
