How to generate fury?

How do you generate fury at such a low level when you take Demon Blades but can’t get Fel Blades.

Legit looked at Icy Veins and WoW Head and it shows taking Demon Blades and same time using Demons Bite

Play Demons Bite at low levels, early on fury generation is atrocious

Either don’t play Blades or wait for your Imo Aura/Felblade to be ready.
