No idea. Decoy was never a great power to begin with, even in single player.
As a personal opinion: I think that calling the change for melee enemies to ignore "pets" (decoys, turrets, drones) as "gimped" or that it "gimped the pets" is vastly overblown. In my experience, melee enemies tended to ignore the pets even before the change; they only focused on the pets when no one else was around. Once they got a visual lock on you, they ignored the pets.
Also note that even if the melee enemies ignore the pets, the pets can still stun, stagger, deal damage, or even kill those enemies.
I think the pet nerf came before I started playing MP but I've tried the Human, Salarian and Female Quarian Engineers with and without pets and in all three cases the class played better without. Combat Drone and Decoy seemed more useful in solo play but in a team they are hardly worth using the cooldown on. Rocket turrent at least could score a kill now and again but I don't miss having it.
And after one (horrifying) game with the Volus Sentinel, I came to the conclusion that he was better with Decoy than the SE due to his mini-cloak but I still couldn't make it work very well. But I honestly didn't like the character well enough to put more effort into it.
Curretly the only pets I use are the Geth turret (offensive on the Engineer, defensive on the Juggernaut) and the rocket turret on the Turian Saboteur. I'll probably respec the TSab when I feel like using a card and maybe the Jugg too.
Pets need a damage buff, badly.

On topic: Loki, I think Decoy + Tac Cloak will still be fine, even if the AI change carried over. Just Cloak, Decoy, and move. The Cloak will let you keep melee enemies at a distance most times anyway.
