Non Pet IO's and the Pets that can Take them.

I have a question. A specific question, and a general question. But first I need to frame it with some context.

In City of Heroes, there are "Pet" powers that can be summoned, that don't accept "Pet" IO sets. Obvious examples of this include the various "Pseudo Pet" attack powers such as [Rain of Fire], [Burn], and less obvious ones such as [Fallout] and [Transfusion].

Some of these "pet" powers accept IO's from multiple sets. Further, some of these pets have multiple different powers, often from each of the Allowed Set Categories that the pet power has itself tagged with.

Now, my first question is related to a rumor I'd heard, and my second question is the specific application of the information I stand to gain from the answer to the first:

I had heard a rumor that if a Pet power accepts multiple types of IO enhancement sets, slotting those types of sets will only apply enhancement bonuses to the powers the pet has that fall under that "category". A simple and obvious consequence, if this is true, would be that slotting Dark Servant with "Essence of Curare" would not do anything for the Accuracy of his Heal power.

Frankly, this sounds like a bunch of baloney to me. Has anyone done testing, or have Developer "Word of God" on this matter? Am I really better off with Generic IO's in these kinds of multi-purpose pets? Or will the Accuracy enhancement in "Essence of Curare" affect his [Twilight's Grasp], [Chill of Night], and [Tenebrous Tentacles] powers just fine?

Now, on to the second question:

The power Carrion Creepers accepts Set IO's of the AOE damage, Immobilize, and Slow categories. It summons a pet that summons sub-pets: Vines that have a slowing melee and ranged attack, and an invisible pet that casts "Entangle", and AOE dot and immobilize.

If I slot a Positron's Blast proc in this pet, will it only proc off the AOE immob? If I slot the Impeded Swiftness Proc, will it only trigger off the Vine attacks?

And that leads to my final related question: Am I just better off enhancing the damage of this power?

Specifically, slotting accuracy, no matter what the set will enhance all the pet's accuracy of all it's powers.

Where the set type comes into play is if the IO is a proc. The game will only check for procs on attacks of the type that is slotted.

Example.

Dark Servant can slot Neuronic Shutdown: Chance for Psi damage proc. This proc will only have a chance to fire when Dark Servant uses a hold power, not everytime the fluffy attacks. This does not effect enhancements, just procs.

(On a side note. Pets are not effected by recharge. Slotting recharge does not increase their attack's recharge, nor does Speed Boosting them. This works on the other side in that slows also do not effect them)

For your specific question:

Carrion Creepers has poor damage and throws out tons and tons of attacks. That power is meant to make love to damage procs.
