I don’t want to give away what I use precisely, because maybe there is a more creative and better version of the build that you can create.
But the idea behind it is to Skull Crack with the new Berserker’s Power trait, then switch to GS and apply as much 100b as you can before they stunbreak. Sometimes you spend a long time baiting a million stunbreaks out of people with Mace #3, Shield #4, and even “wasted” Skull Cracks. Shield #5 is also a welcome 2 seconds of breathing space in an insane burst meta
Honestly I think this is a pretty boring and incredibly predictable playstyle for warrior, but even with glassy amulets I can stay in a fight a lot longer than with other builds – since you get more “breathing space” by shield’s block, GS whirlwind, and the fact that you are temporarily stopping one enemy’s output with all those dazes/stuns.
