omg, that's awesome. You hit while raging to give disadvantage via ancestral protectors. Even without swashbuckler, you can cunning action disengage leaving opponents with disadvantage and (barb5) even go, try and hit someone else. (Allies next to the hit opponent or who can get next to them before their turn will get opportunity arracks if the opponent pursues). With swashbuckler3 you can, Fancy Footwork, ... slip away without opportunity attacks from creatures you attacked. You could then cunning action dash with the likely result that, at best, they could just dash to get to a space where they threatened you. Otherwise, they might then be limited to ranged attacks - if they had them. Other otherwise, they might alternatively try to retreat (if there weren't obstacles preventing such movement) but your own ranged attacks could sustain your rage while closing back in on them again.Path of the ancestral guardian might be great fun too, if you want to have the enemy focussed on you and not your team.. Might really play well with swashbuckler. ...
Bugbear is great but, with cunning action dash, even halfling, with ability to move through opponent's spaces, might be workable. Who needs to tank when you can force your opponents to pursue you away from your allies?
