By the way, here is MyDDO link to the project character:
As you can tell, little thought went into this one. Took a bunch of two-handed fighting feats, improved crit, cleave. Frenzied Beserker. Pretty basic. As long as the hireling is upright, the HP are enough that no melee enemy is a threat. Just like PD, it's a matter of getting the casters down before they get multiple spells going or CC me. Parvo the Barbarian's weaknesses are will saves and elemental damage.
