Instead they went with "You need to follow this half demon elf mega sourcerer because you suck and it's the only way to get better." That is not the theme I expected or wanted for my character that was supposed to be godkin, inheritor to the divine. I would go as far to say it felt like a slap in the face after what the events prior built up.
You start the game as nothing, no source or divine powers, what choice do you have but to follow Malady really?
Also i don't get why people call her omnipotent, you know that travelling from Hall of Echoes can actually kill her? On one of my playthroughs she just collapsed and died at the start of Act 4. Such omnipotency right?
