The idea of this build is to take advantage of the every 9 fury generated to add another second too wrath of the berzerker. the ancients are there essentially as defense and to keep some of the aggro off you since you have almost no defense. Weapons master is on so you can use mighty weapons for an additional 1 fury per hit which will come in handy assuming you can get roughly 1 hit per second thats another 2-3 seconds depending on how long is lasts. the rest of the skills are based around getting percentage damage up and using frenzy as your primary attack. definitely could be tweaked a bit but war cry and ground stomp are there to be used immediatly after wrath of bezerker for a quick extra 10 seconds of wrath then it can be used again for another 10 seconds later.
essentially with this build wrath of the berzerker should be up about 40+ seconds if executed properly. the ancients will also be around almost all the time as long as you are on the ball.
I'm not sure if this is better, but it's what I'm going to try. As long as there's always monsters around I should keep wrath of the berserker up with fury and casting war cry and stomping every cooldown. I'm hoping that the 20% movement speed is enough to make up for not having leap/charge/spear. I'm also not sure if it's better to have 47% dodge or 50% life and life regen rune. If overpower doesn't proc often or the aoe damge from it isn't that great, I'll swap it out for seismic slam.
