Doesn't have enemy only mask.

I don't think they had any choice but to go (+4 x -4 all) for each of the forms. A S4 guy who shapechanges into a D4 guy won't end up with just D4. You have to do it using boosts (which can be to specific paths) and an overall malus (which can only be overall iirc, specific ones don't work properly).

I would consider the use of this to be an exploit. I'm sure Foodstamp, K and others would consider it to be a balancing part of the game which if removed due to people whining, would diminish their enjoyment.
