Just useful. For what it's worth, I think you're looking for guaranteed kills - or at least I got that impression with your comments about drag. If drag/shadow drag worked 100% when perfected, I could knock someone out and drag them into a myriad of 'cannot escape from' sorts of locations and they'd be pretty much guaranteed to die.

Dropping someone's morale is useful, depending on how much you can drop. If you could drop say, -50 morale, it'd be borderline overpowered. If it drops -5 morale its useless.

But based on the effects, it *might* be useful. That's all I'm saying.
