While looking through the handbook for Mindjammer I came across the rules for dealing with different scales, which struck me as somewhat different to the way other fate-based RPGs handle it. In Mindjammer you get +2 when attacking a target per step above you in scale, but deal 4 less shifts if you hit, and the reverse is true for smaller targets (harder to hit but dealing more shifts of damage).
It seems to me that even if that +2 to hit allows me to hit something I otherwise would miss, the reduced damage would make this count for the same anyway. Is there any real reason not to simplify this rule to have -2 shifts per step above you in scale, and +2 per scale below you? It seems at first glance that you would end up with the same amount of shifts, but I feel I'm missing something that would make this change screw up the game balance.
