[3.1] CHILL POET BERSERKER - Non Crit, Shatter, 8K+ Life, EZ Playstyle, Shaper and Guardians down,

Hey guys, i've tried this build and is looks great at moment, the unique change i have make is take off Crave of Slaughter ascendancy point because degen of rage is painful.

So the only problem i've seen on this build is the leech, i can't leech against trash mobs, the leech only work when i got a savage hit (mostly from bosses), só i need some help with this.

How i improve my leech against trash/rare mobs ??
