I just don't think its fair to make any assessment of her yet, good or bad. I also don't agree that she was a damsel in distress. 2 things about that issue stand out, especially in hindsight. 1st everyone on it needed to die because of the reveal of the 5 and mutant resurrection. Second as far as Jean herself is concerned it was made clear that she had to maintain contact with Xavier back on Earth millions of miles away and that was her most important job. Its also implied in the art that she was injured in the initial explosion. Lastly she was maintaining psychic contact with her family (and Earth) as they were all dying, that's got to take a toll. So i'm not willing to immediately go to yelling about regression.
If it continues I'll concede it as a fair argument but 1 fight does not a trend make especially one that had as many extenuating circumstances as that did.
A little more context, 1 fight in a series she wasn't a star of, that was about setting the stage more than anything else.
