According to this thread, the least useful powers are decoy and defence drone.
How would you get the most of these two powers?
Decoy: requires Infiltrator with Tactical Cloak rank 6 Free Power. Infiltrator cloaks, rushes forward, places decoy, rushes back. Begin shooting the enemy.
Defense Drone 1) Use on Engineer, use with Combat Drone and Sentry Turret. Ideally with Tali for another Combat Drone. Run in and hope everything is staggered and shoot everything to death.
Defense Drone 2) Use on Infiltrator. Cast Defense Drone. Start sniping. Hope Defense Drone staggers enemies that happen to flank you while you are zoomed in sniping.
Decoy's biggest shortcoming is that it is placed about 1-3 feet in front of you and does not move. Decent for narrow hallways, bad for more wide-open areas. Best used with the Shock evolutions. Decoy also has a limited duration unlike Combat Drone and Sentry Turret, which will remain until destroyed or no enemies remain. The duration is not a big issue, although if you take the Explosive Decoy at rank 6 then its duration is unbearably long.
Defense Drone's biggest shortcoming is its delay in following you. It has some decent range as a drone, but it can get left behind if you need to move quickly. I tried using it on a Soldier once, but since I was doing a lot of running I would run out of its effective range and so it was not much help. Its fire rate is also rather long, negated somewhat by the evolution that inceases its fire rate (rank 5 if I recall).
Defense Drone also has a limited duration--unlike Combat Drone and Sentry Turret which will remain until destroyed or no enemies remain--but the duration is not listed in-game; there is an evolution at (I think) rank 4 that will increase duration by 100%, but without knowing the base duration, that evolution is meaningless.
