spotting when turning around your units

[RERomine]

I'm not sure it is really unfair, since everyone has the ability to do the same thing. If one side has an edge in troop numbers, they might be at a disadvantage in experience. A more experienced unit can spot better than an inexperienced one. When you boil it down, however, the more eyes you have searching, the more likely you are of spotting the enemy. I don't see anything unfair here.
