I decided to re-spec as a Vanguard, and you guys weren't kidding...that is a seriously devastating build. The shield regen/restoration turns you into a wrecking ball with an asari sword. The only thing I have trouble with are big armored enemies like hydras, so I usually switch to incendiary ammo. Charge/Annihilation/Backlash has been a nice mix, but sometimes I feel like I don't need backlash, and could try something else like Shockwave or Nova.
