I can't actually remember whether it was a reddit or a forum post that said that a character's location on the map should matter much more than it did in CK2, and I agree fully, because in CK2, character location only really mattered for commanders and councillors, and it was extremely unrealistic and baffling that a character could teleport from Ireland to Jerusalem in a blink of an eye. I think it would be very cool and good for rp if character's locations were a much bigger factor in CK3
