It depends on what you do with your barbarian really. The build you can make and what you’re running.
The build I use is very fast and consistent. Faster than any of what my friends play on the other classes, rogue too. I don’t use shouts or the usual big hit builds.
I lunge with incredible attack speed, dual-wield swords, perma-berserk, leap and whirl/double slice through everything with 50/100 crit chance. It’s a ton of fun, but it can’t really run super high stuff sadly.
What level are you at the moment?
Some classes are slow going at first, some builds are doable earlier than others.
