Just lvled my barb with some gear, need some advice on gear/skills.

1)Zerker? WW?
2)Weapon/gear choices

CB gear - no different than gear for dclone, howl for crowd control (getting swamped by a bunch of concentration powered mobs is a "killer").

Just don't forget to have a life tap dagger|wand ready, or a pair of Marrowwalk, for when heralds come with thorns aura.
Additionally, be sure that your char & merc both have no chance to overwrite life tap, on the herald himself, as well as on all surrounding mobs if you decide to take down the whole pack.

Appreciate the tips guys! Im sure once i do a few runs ill learn whats missing from the build.

If I were to go sunderhunting with a barb I would make it a caster/singer who can bo a team and hork efficiently.
Stack him with mf gear and + skills gear and afk in town of a p8 game as a filler, who asks for a tp whenever a herald dies.

I have seen several of these barbs in my split runs and they actually tend to find more sunders than the actual hunters.
big bonus is that they have watched 2 movies or done some work in between as well.

This is more passive way way

I tend to hunt/hork myself and hork for other players, if they call for it.
