Oh, and I just remembered another brought down for Storm to prop up Jean Grey.
There was a story where Gamesmaster mind-controlled all of Salem's population. Before doing so, he incapasitated Jean because he considered her a threat. He then proceeded to control the whole town's mind, including Ororo's. Anyway, Jean woke up from the trap and got ready to challenge Gamesmaster. Not sure he could win, he chose to flee rather than face her in psychic combat. It took his full power to mind control that town.
There is no way Gamesmaster should have been able to mind control Ororo, but this kind of Storm portrayal was par for the Lobdell/Kelly/Seagle era. I can't even recall a single issue during those years where Storm's willpower was even called "indomitable".
