Ending up on the other side of the board is not always "utter fail". Often times it is just not the most useful place for you to be. It really depends on what's going on in the battle and what unit it is that's comming in, but in either case "utter fail" is not a foregone conclusion.
I think things are more or less fine as they are and having your opponent chose which side you come in on is something that shouldn't be added in with such a limited range of possibilities. Maybe if board edge was decided on a
2d6 roll of some sort then you could add it in.
