Weaknesses have always been to me, a thing that causes hindrance and/or harm. Things like arrogance, yes we should not include. That isn't a weakness, that is a character flaw. People should know the difference there. However if you have something that hinders a character such as a cold gun, then you got to put that in.

Invincibility leads into a different story. It is a power in which no matter who else is affected by that weakness to the invulnerability, we put it in. Because to everyone else, invulnerability means no weaknesses until we tell them otherwise. So we list everything that has been known to affect it.
