... that one mission where you rescue the quarian from the varren. I've got a buddy who can't get past it on Insanity and would like some tips.
Here's his build.
Don't worry I already chewed him out for playing an Adept on Insanity.
Tell him to reroll an ammo ability (I went for Warp or Disruptor or Armor Piercing... cant remember). Adepts on Insanity are still viable. Be sure to take "Sniper Rifle Mastery" when you assault the derelict Collector Ship.
Also, Thane and Miranda are powerful allies since their Warp Powers melt Armor/Barriers.
