I like it, but I do miss out characters canonically learning from our experiences.
Back around the Wrath/Cata/MoP era our characters would learn new skills based on raid or dungeon boss abilities, and it really felt like our characters would pick up new abilities from their adventures. Since borrowed power came into the picture with Legion they could have been letting us learn our Artifact abilities or Azerite traits/essences permanently, baseline or talent, but those that have done so have generally replaced other abilities or talents.
I still feel after Legion we could have had a new talent row based on our artifacts quite happily.
