Some theorical question for optimisation :
Does the demon blades talent work with the potency conduit “demon’s touch” : so basic attack can buff abilitys ?
Same for “burning wound” Legendary, does it make demon blades proc a buff on immolation aura ?
It would be a huge oversight and force that talent even further away if it wouldnt affect both. If it is not working I think that is more likely to be a bug then.
