Um...not on Republic Side, at least.
Remember this was a Medium Armor
-based, with Shield
Rating. Now let's look at all the companions:
And I just looked over the list of Imperial classes and their companions, none of those are medium armor, cunning, shield-using folks either.
So I don't see how there are any companions that truly benefit from an item with this particular itemization. Sure there are plenty of medium armor, cunning-based companions...it's just that not a single one of them needs shielding. And there are plenty of heavy armor wearing, shield generator equipping companions...but every single one of them is Aim-based, not Cunning-based.
Unless I'm missing something, or all the fansite info on one of these companions is incorrect.
