I agree with this statement. Origins had some fetch quests as well, but at least the cutscene conversations made the npcs feel more real. When I'm being told to collect bear claws by someone whose face I can barely make out, I have little reason to empathize with their situation.
Most fetches didn't have dialog nor most sides, let alone sides. Take the Deep Roads
Places of Power - No dialog, delivery quest
Topsider - Fetch, no dialog
Asunder - fetch, dialog (after)
Gangue Shade - no dialog
Legion Armor - Fetch, no dialog
Drafter's Cache - Fetch no dialog
Registry - Fetch no dialog
Ruck - Dialog
I think people forget the long list of sides that lacked dialog. Compare with the hinterlands, the most notorious area
Farmland Security - dialog
Trouble with Wolves - dialog
Master of Horses/Horses for the Inquisition - dialog
Hunger Pains - Dialog
Love Waits - dialog
Business Arrangements - Dialog to finish
Where the Druffalo - Dialog to finish
Agrarian Apostate - Dialog
In the Elements - Dialog
My Lover's Phylactry - Dialog to finish
Strange Bedfellows Dialog
In the Saddle - dialog
A Spirit in the Lake - Dialog
Flowers for Senna - Dialog
Ballad of Lord Woolsey - Dialog
That is 15 out of 40 someodd quests and that is counting all the rift quests, map quests and astrariums separately,
