Just started new DH on season with no other character.
What's the best/most efficient way to farm up Marauder set?

My current build:

Currently I can 1-shot everything in normal, and 1-shot T1 white monster with Cluster Arrow:LFB. But doing T1 must be solo, if in group my damage will just tickle the mobs.
