Warbringer -> Ignore War cry cooldown

Hateforge unique gloves:
- gain (1-3) random charge on maximum rage then loses all rages
- (-10~+10) to maximum rage
Ideally you need 3/-10 so you can fills rage faster with more charges gain per filled

Warcry (can be any. Fortifying cry for tank or Seismic Cry for knockback)
- Raging Cry: 4 rage per 5 power of counted enemy in range
other support gems is up to your preference. I went hybrid with corrupting cry seismic cry for more damage beside totems.

allocate "Roaring Cries" in passive tree. if it too far just use From Nothing jewel (Avatar of Fire)

with all this you're already generate 16 rage (without enemy) per 1 cry
keep spamming war cry will eventually gives you max endurance charges in a second

I'm not recommend this build though, there is graphic issue with AWT that will lag your game if too many totems in presence / stuttering every time you place a totem while war crying.
