i voted for no limits on fast travel. i'm with Icelyn i like going where i want quickly. On the other hand, i voted for random encounter. i like to see larian implement random encounter in baldur's gate 3. or even a random dungeon or area of some sort.

random encounter will solve the problems of "merchant farming" where are no other means of getting loots/gears/items as encounters are limited. monsters that we fight in random encounters, i believe larian can make it so that they gain little to no experience at all. the rewards of random encounter is the battle itself! and of course the loot. i like to see an area or maybe some sort of dungeons or random areas with different level of enemies the deeper you go.

that will be really great IMHO.
