They ruined the entire plot and still expect applause:)
It might work as a strategy game, but if the plot isn't coherent, it can't be called Heroes of Might and Magic 5.
I would agree with the idea of setting the action on a new, remote planet discovered far in space, where different laws apply. Adding a story about the Ancients would be great. The world of Kanehelm offers such possibilities since the universe is limitless, so why abandon it?
