I just used strong abilities that mostly guarantee one shots. I ran top tree void for warlock and used bottom tree arc strider with sticky nade with max discipline on hunter and an smg with demolitionist. I have no idea why no hunter is running arcstrider with this grenade, its seriously busted. The grenade is basically hitscan and then you can dodge after you toss it and walk away because the enemy player is guaranteed to die. You could also use throwing knife, its just as easy to use. You can even land a few shots and finish off with the knife
