For ME, not having movement paths is a borderline deal breaker, but I understand not everyone feels that strongly about it.
Not having this feature is a HUGE problem for me personally, because I find myself feeling frustrated every time my units do something I did not want them to (or every time I move when I have to do it manually square by square all the time which undermines almost the entire playing experience because you spend a good portion of your time every turn moving units). Personally, when I start feeling frustrated or irritated too many times when playing a game, I slowly stop wanting to play it.
I understand other people might not feel the way I do, but I really really wish they would at least put the movement paths in even if implementing the ideal "stop movement and ask for new orders" function is too much trouble.
I know laymen always tend to underestimate how much time it takes to add new features to a game, but with my limited programming experience I really can't imagine basic movement paths would take very long at all.
