[M&M 2nd ed] Alternate Form power question
Hello, I've a question in regards to a character of mine
I've a paragon with Enhanced Strength among her powers, and was looking to pick up Alternate Form as some point (turning into a creature of cosmic energy). Among the powers this alternate form would have is Insubstantial 3 to be made of energy.
Would exchanging out the Enhanced Strength while in Insubstantial form be an alright option (allowing points to be freed up for giving off an aura or more flight or something)?
Just the Enhanced Strength mind you, not the natural strength as that certainly just looking for trouble (dropping Strength entirely and getting much of the cost of Insubstantial paid off, doesn't sit right)
Perhaps the current powers need be loaded into a different "container"?
I know that the Shapeshift power allows changing of base attributes (at least according to Hero High) like Attack, Defense and Strength, including reducing attributes outside the power. Now obviously that's a variable power, but does that suggest that a fixed power might make a fixed reduction in non-mundane powers?
