My observations exactly. I was able to get all kinds of demons, executioners, cerberi, imps and dark paladins, as I usually use them for a phantom-res tactic close to the end of the fight.
Allrighty, so it does work, we just need to make it work
EDIT: Ok... while I understand why the devs wanted to make burning, poison, cold, etc. more viable, this is kind of ridiculous. Since when we can't remove those conditions? Dispel is like the worthless thing ever now.
