There is no need for more vitality on a Barbarian.
If anything you'd need more STR/DEX to efficiently try and kill the monsters before they kill you.
You'd generally need something that can crit well if using a Melee character to well such as a Club, Dagger, Sword, etc, especially when not using a Heal Charm with a sufficient Mana Pool.
I personally had a decent pass rate on my wells when using clubs.
