More DR and more fury generation. Running 2 - 3 shouts is meta for a reason. I can’t imagine playing the game without the DR and Unstoppable at least, I would just get deleted. Make shouts worse, but make the party buff portion better (longer duration for example), then buff fury generation from basic skills and make the baseline barb not feel like a sheet of paper in whichever way you prefer - more armour/DR/block/DR or Unstoppable while Berserking/whatever floats your boat. That would make running other skills much more compeling, because the problems we try to solve by shouting would not be as severe, while Shouts remain good multiplayer option.
