[DAV Spoilers all] Previous DA companions would stick out like a sore thumb in Veilguard
Consider the Veilguard party members, who are mostly straightforwardly nice people with very little disagreement amongst themselves, dealing with any of the following as they were in their first appearances as companions:
-- Sera (self-loathing elf)
-- Oghren (alcoholic sexist who's an absentee father)
-- Vivienne ("fuck you, got mine" mage embedded in the power structure)
-- Dorian at the start of DAI (otherwise lovely guy who uncritically supports slavery)
-- Aveline (cop)
-- Nathaniel (nobleman who tries to assassinate you)
-- Zevran (sexually abused assassin who tries to assassinate you)
-- Velanna (terrorist)
-- Anders (terrorist)
-- Sten (authoritarian zealot)
I do not think any of these folks would get invites to the book club!
