Re: Companions aren't bantering?
30 hours into the game and I've heard maybe 3 or 4 bits of banter. Playing on the PC.
When exploring the Western Approach I was lucky enough to have two bits of banter in quick-ish succession (around a 5 minute gap). This was between Blackwall and Solas and then between Blackwall and Cole.
The only other banter I distinctly remember was between Varric and Cassandra when I first entered the Hinterlands...
It may be linked to companion quests in some way since I'd collected a grey warden relic around 2 minutes before Blackwall started bantering, but that could've been a happy coincidence.
