Was this actually that common a complaint?
One of the most common ongoing complaints for pretty much the entirety of the game's lifespan. It was so bad in fact during Early Access that my
very first thread ever on this forum was literally to prioritize the main character during dialogues
It keeps being an issue because all party members become instant avatars without their established personality once in a conversation (due to the game having co-op), so Lae'zel talking to someone like Mayrina makes as much sense as Astarion talking to Zevlor and promising he'll rescue the tieflings. It keeps contradicting established characters whenever they're pulled into a dialogue over the main character and by doing so breaks immersion, which is why it's constantly an issue.
Naturally numerous improvements have been made over the last three years, but it's still an issue from time to time and back in the day you would not even gain any approval whenever companions used to take over.
