Couple ways
1- Mook Asploder. Acolyte Pistol for Shields/Barriers, then Pull -> Reave. Switch to a Piercing SMG for bosses. Pair with biotic teammates and spam Reave while they spam Dark Channel or Warp or whatever.
2- Radius Warp Bubble. You can Reave -> Bubble -> Reave for combos against all defense types, even armor. It is a high risk high reward playstyle.
3- Biotic Soldier. Skip Pull altogether. Use Warp Rounds on a Prothean Particle Rifle. AoE Reave then shoot PPR until recharge, then repeat. This setup is a great boss killer, works best with strong AoE teammates. I like to use this build in an all tech team, so that no one is detonating Reave and making me lose all of that Warp Rounds bonus damage. Bonus Perk: Since cooldowns aren't as important, and you do plenty of Shield damage, you get to take a Scorpion instead of an Acolyte.
4- Pizza Delivery Girl. Grab the Pizza, turn around, look slightly downwards, and spam your Omni Button to repeatedly dash backwards -> grab pizza -> repeat. Drains your barriers but gets it anywhere in the galaxy in under 30 minutes or it's free.
Addendum1- Bubble will always detonate, even if you don't take the Warp Evolution at Rank 6.
Addendum2- Bubble does 1500 Force, so you can use it as an on-demand stagger vs bosses and save the pug from banshee hug.
