As an asari adept that beat gold, I say throw primary use is killing turrets and atlas. Warp+Throw destroys shields and armor very quickly, and I would say that biotic detonation upgrade is a must, I would use that on people too, but stasis is a lot more effective, detonating stasis with throw on the other hand is useless, in my opinion, by the time the recharge is done the target should already be dead from bullets, and a new stasis should be cast right away on the new one, instead of damping cooldown on throw, even if it is fast. Throw is also good as an "oh ****" button when you run out of bullets, and to blast enemies that you can't see, through curving, so you don't have to expose yourself.
