Here’s my build. Ignore the empty slots as I only filled in the stuff that I think matters for fury generation.
The most important thing I’ve noticed is that it feels MUCH better when you fill up on fury, push Rend, do 2-3 generators, push Rend, do 2-3 generators… This playstyle combined with the Expectant and Limitless Rage aspects mean you don’t really “waste” fury by going over your cap and your Rends do more damage while you keep your fury up.
I take the +24% shout duration (Booming Voice passive) combined with Echoing Fury and Bold Chieftan aspects to get massive fury from shouts.
I’m wearing 100,000 Steps boots that generate 40 fury when I push Iron Maelstrom.
I use the Rapid aspect on a 2H weapon to get +50% attack speed on basic skills. This is HUGE when it comes to generating fury with Lunging Strike a couple times between Rends.
I’m wearing Ramaladni’s sword and it generates big fury when combined with the fairly high Lucky Hit % on Lunging Strike. It also makes Lunging Strike do big damages when you’re close to full fury.
Rage of Harrogath chest reduces the cooldown on shouts by a lot, so it’s a must since more shouts = more fury per second.
