There’s a defensive talent that make you run faster and take less dmg up to 20% while in Ghost wolf, which can be combined with the Azerite trait Pack spirit who heals you for 2,5k / sec at 390 Ilvl. Stacking this up to 3x you can reach a 7.5k passive health regen per second while you take 20% reduced dmg.
but it don’t end here, you can also pick up the pvp talent “spectral recovery” which will heal you for 3% of your max hp every 2 sec. ~200k hp = 6k hp / 2 sec.
So if you stack everything Ghost Wolf related you will have -20% dmg taken and about 10.5k passive regeneration per second while moving at 160% of normal speed or can’t be reduced below 100% movespeed.
