Tips for double kills and sprees. Having a "Militias Birthright" or any non heavy GL helps out a bunch. that way you dont need to wait for heavy all the time. Having a play of the game with blast radius, volitile launch and prox nades is the best. You can easily one shot guardians and potentially get 4 kills per brick. The best place to get kills is Mayhem. Use a tether with Orpheus Rigs. Either tether a few and kill one with GL, they all die. Another option for 3 kills in one life, Use top tree tether, use it as a lure. Shoot at the close side of a corner, you back up around another corner so you cant be seen. When an enemy is lured in by the tether, they get snagged and you blast them with MB or Fighting Lion. Its still a grind, but i find its a steady way to make progress
