Any point in enchanter debuffs?
 

Obviously not speaking about slows but instead the stat type debuffs such as weaken and disempower.I've heard conflicting advice from others.

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.

I've read not to bother with them here, on live every sham/enc I grouped with would use them after slow.

Maybe stat/ac debuffs always been kinda moot but it wasn't really common knowledge back then.

The resist rates on the only mobs worth using them on is too high for them to ever land. Just skip them.

Heard they're good pvp...particularly against casters

They are effective. Cripple makes spectre hits drop from the 80-100 range to the 30-40 range. Slow is more important, but the stat debuffs really turn mobs into pussycats.
