Should returning be overridden at all?

Returning and retreat are different in one major aspect: returning allows to safely escape from assassination attempt and from province surrounded by enemies while retreat doesn't. OTOH, Returning is heavily dependent on the home province, however if you lost your home province, you probably already lost the game as well.

Retreat has a counter, which is putting troops behind the Retreater...which is countered by Flyers that Retreat, and is countered by Storm....which is countered by Flyers who can fly in Storm....

This game is based on counters, so Returning needs a counter (and no, killing the mage is not a real counter since it works for any effect). Sure, "taking the home province" may seem like a counter, but it really isn't since it implies your opponent has already lost and really doesn't need his stuff countered.
