I don't want Storm to be limited to some Earth-based pantheon. The evidence in Storm's history points to her being potentially a universal or even omniversal power. I don't mind various pantheons of gods showing up in her series (some for friendship, others as foes), but don't make her one of them.
The problem is the writer may believe Thor to be the stronger elemental of the two and write her down in an effort to emphasize that. Look, Storm and Jean have very different powers, yet Ororo is scaled back everytime Jean joins the team. I also believe she has been scaled back for Iceman and we know for a fact she has been written down to prop up Magneto. I don't like Ororo with other elementals. Writers tend to scale her back to make their powers relevant.
