her becoming a goddess gives her a potential new rogues she wouldnt have under her current powerset. if done right she could be one of the heavyweights that are called on when threats to the eart occur from villains such as Galactus or what we saw in BP book actual gods. So it's a reminder, for those who like to exclude her, she is a powerhouse. Also, this is as I said before something that Claremont hinted at himself years ago. I think the goddess power can be something she taps into on when the threats warrant it. So when she is fighting your typical xmen threat she can hold back and do the typically lightning strike stuff she always does. But with threats such as the one in gold she could tap into that ability to defeat them or at least give them a good fight as opposed to seeing this hammer crap guggs gave us.
