Any advice on what skills to utilize and how to approach my merc?

Most of the wc tree
Bo
Taunt or the one that drags individual monsters

Safest route would be these in my opinion: for non -frenzy barb I guess.

Max shout,battle orders (40 points)
1 into howl,battle command (42)
Max iron skin, weapon mastery of choice (82 points)
1 into leap, leap attack, bash, stun, concentrate, whirlwind, berserk. (89 points)
Rest into natural resistances.. ( maybe waste 2 points for increase stamina & speed if wanted?)


Would give u best defense possible,best life possible, Whirlwind and berserk being ur right side, concentrate being ur left side?

Im no pro but it seems like the common sense safest route.

yikes.. max iron skin


depends what you want to play.. warcry, zerk, frenzy, ww? builds are completely different. typically you max main skill/bo/mastery of your choice/rest in shout/synergies.
1 in leap, nat res, iron skin, inc speed, battle command. can put a couple into nat res/iron skin if needed, for nm/early hell.
1 in taunt & battle cry is a really nice help but not needed.

Frenzy or fall asleep.
