Is Backlash Overpowered?

Hai Guyz,

I completed my first run on Hardcore. I had a "sentinel" build(biotics and tech, backlash, singularity, energy drain, incinerate). I'd oftentimes kill several enemies at once simply by holding up my Aegis until they killed themselves. You'd think that the Annointed would stop shooting or aim somewhere else rather than kill themselves. Anyway, I really love backlash, and thought that it needed it's own thread.

On a semi-related note, I am trying to do my second run on a gun-heavy infiltrator/Soldier, who uses consumables(Barrier and land mines) in places of powers. So far it isn't going so well. It is hard to get the enemies to walk over your mines.
