I am not a fan of random encounters. For me they slow down the pacing too much. I like how fast travel currently works in BG3. I like that BG3 doesn’t waste my time with lots of trash mobs or doubling back.
No one wants trash mobs or tedious uneventful doubling back.
That's not what is being suggested here by asking for fun meaningful random encounters or repopulating dead areas with creatures, or changing fast travel so it could be interrupted by said creatures.
