Question about Mids and dominator ATOs

[EnjoyTheJourney]

For an earth / dark dominator build I was able to slot the dominator +dmg proc into the secondary (midnight grasp) in mids and in-game. But, I can't do that for Bitter Ice Blast for ice assault. 

 

Edit: I checked by trying to insert the dominator +dmg proc IO into bitter ice blast and found it doesn't work in-game, and Mids suggests it can't be put into bitter ice blast as well.

 

As a working hypothesis, perhaps a power must have an effect labeled as "control" before a dominator ATO IO can be slotted. Is that correct?

Yes if an attack in your secondary comes with a side benefit of a stun or immobilize and any other kind of "control", except likely slows, then yes you can slot it there.  Typically a blast won't have the ability to slot it but a melee attack can.  Your hypothesis is correct.  😜
