In practice none of them really do any damage compared to stacked archers.
Highlander does outdps barb a little on bleedable mobs but that’s it. Meanwhile he’s contributing with armor crash, pierce stagger and crown making even some magic lv 270 world bosses deal 1 damage (and blocking hits is vastly superior to running around bosses constantly). Barb skills have too long CD to be really good unfortunately. Neither frenzy or warcry have any reasonable uptime sadly and their real damage comes from doppel circles which is what highlanders will probably take as well.
This philosophy on low rank classes not scaling is really hurting any dps oriented classes on early ranks. Same deal with pyros.
