However, a character with Incorporeal +8 is only able to float through a few materials...most objects, IIRC, have more than an 8 Hardness. Furthermore, Incorporeal is already hamstringed through the use of HP/VP...just give yourself the Ghost Touch Extra for any attack. Combined with the weak form of protection offered by Incorporeal under Calinon's version, it seems very weak. You essentially gain only the ability to float through a few forms of materials, while gaining Protection against everything except for one form of attack. And you can't hurt anyone else while Incorporeal (unless you use Ghost Touch weapons, or something similar).
Just pointing out flaws...much of M&M is unbalanced...Boost and Duplication immediately come to mind. If that's what we're using though, fine with me.
