Caravans are already slower than ox carts, which is a big annoyance. Making it worse will just make the caravan system that much more annoying to deal with.
well.. old caravan (as in when caravans were 1st introduced).. 1 region per turn . current caravan. 1 region per day. but the description in the game does say trips cost X days.. as opposed to X turns..
now... they don't have to make everything slower than current, because as it stands, if you set a caravan trip, it won't start moving until the next day... so.. you can say that can correspond as what will happen with no caravan shop. thus, if there is a shop, they could start moving immediately. and starts selling in the next region the next day. thus speeding things up.
