Reactive Interface in Mass Hypnosis?

So I'm finally starting to incarnate-out my mind/psy dom and I'm wonderning about the interface slot. I know the reactive DoT proc breaks mezmerize (which I can live with), but does it also fire off with Mass Hypnosis? I searched the forums and found two posts which stated the exact opposite of each other.

Next question - if the DoT does break the AoE sleep, should I just go with the 75% debuff - or is there a better option? (I solo frequently, so the AoE sleep gets a lot of use.) Any opinions would be welcome.

mass hypnosis does no dmg and thus the interface procs wont fire on it

More specifically, Mass Hypnosis can't accept Damage Enhancements. That's what the Interface slot looks for.

Thanks for the replies. I thought that's the way it worked from the description, but just wanted to be sure.
