What was your favorite bonus power?
My current favorite is Incendiary ammo. I went ages never playing with Zaeed and I recently decided to stick him with my BroShep just because I couldn't really think of anyone else to use and OHMYGAWD is his grenade brutal. LOL.
Prior to that I usually went with a power that rounded out my Shepard a bit. A non-Biotic got a Biotic to throw (usually Slam) and a Shep without a ammo power got an ammo power (usually Warp, but I have developed a fondness to the way the Shredder ammo... well, shreds, through the Collectors during the End Game).
Anyways, what is yours?
I haven never used Neural Shock, Geth Shields, or Dominate. Nor Armor Piercing ammo.
