so the question is more of "does it effect your pets that cast" i dont have the trinket so i cant test this, but that is unlikley
as it says "increases your cast speed by X"
not "increases haste by X"
it will not effect your pets attack speeds, but slightly may be possible for it to increase your imp/doomguards casting speed however i doudt it, but its worth a try
also whats your question on the scaling of our pets? you say you have some but never ask them?
