Right now when you right click or mouse over a weapon, the damage range shown is with the bonus from MIG taken into account. This makes it difficult to compare weapons that different characters are using, because if these characters have different MIG values, the same weapon equipped by both will show different damage ranges.
How it needs to be shown, instead of (for example) "Sword: 16-22 slashing damage", is something more along the lines of "Sword: 15-20 (+1-2) slashing damage". Then show the net damage elsewhere on the inventory screen as suggested in http://forums.obsidian.net/topic/6
