Giant-Size X-Men #1 gives a good example of what Lorna can actually do when she gets to contribute. The rescue doesn't end with everybody simply beating Krakoa up. Her magnetic powers are part of the coordinated effort that gets the island off Earth. That's a substantial job in a story introducing an entire new team. Then she and Alex leave in #94. They want out. Fair enough. By #97, Eric the Red has them under his control and pointed back at their friends. That's also where the Polaris identity comes in. Even a major step in establishing her superhero identity happens while somebody else is directing her. The book has already shown her ability. It keeps putting a controller between Lorna and whatever she could choose to do herself.
