They've been "subverting expectations" for so long...
...that at this point having a roster played entirely straight without Dramatic Tragic Backstories consisting of something like an alluring but aloof witch for men, an honest noble handsome knight for women, a gruff but well-meaning dwarven brawler, a pure-and-innocent cleric girl that doesn't serve an evil cult, and a wise old wizard who isn't "secretly" a sex pest will be subverse all by itself.
When did we stop getting companions that weren't most-original-Tumblr-OC-evers in RPGs? Around 2014, when DA: Inquisition came out, becoming the herald of what's to come? There was also Siege of Dragonspear and the debacle that rose from it (and which had a homosexual quirky gnome as a party member - I guess that's where WotC first enacted their mandate in regards to that stereotype which is all over BG3).
And you could feel Obsidian losing Avellone taking a toll on their companion writing. He seemed to be about the only example of someone who could reliably make zany characters that weren't insufferable or were insufferable by design (Durance).
