Roles are now pointless in lvling dungeons

It is possible. Just being careful with the packs, the big mace orges and killing the sentries.

The big ‘I’ll break you upon my body’ isn’t bad outside of his one shot which… still one shots even in ultra optimised TW gear.

WW with HoA, Cloak (BfA 8.3 or Mop), Chromie timed Bladefist weapon, 3 piece Deathwalker Horde Azerite set, Hand and Leg 2 pce current tier, embellishment Wrists and Waist, stat trinkets from Legion and WoD will be able to solo tank it as DPS. WW scaling for TW is whack as a baseline, but you can make it more so.
