To be fair, we hardly know the inner machinations of any of the characters in this run. I have no idea what Betsy is thinking or feeling over in Excalibur, and she is the main character.
To me feats are important since they remind us of Jean’s power level. One of the things that I like about Jean is that she knows that she has these terrible energies inside of her (to quote Apocalypse), and it scares her a bit (what would happen if she cuts loose completely, how much damage could she cause?), and at the same time she is really drawn to these powers of hers (what would happen if she cuts loose completely - how wonderful would it feel, would she be able to stop?).
If all we saw her do was read people’s minds and float, the above aspect would lose its impact. So I need feats every now and then.
In the future (hopefully 2022), I would love to see them fully explore what makes an omega level telepath special. Telepathy can be used in lots of amazing and scary ways and I would love to see them be creative with Jean.
I would also love to see Jean do some cool stuff with her TK again. Teen Jean did things with her TK that Beast said was Phoenix level stuff. So adult Jean should be able to do that as well. She may not be an omega telekinetic, but she is still VERY powerful.
And yes, I would love to feel closer to Jean again. To know what she thinks and feels. How is her relationship with Scott? I would love to see that explored more. I know that many people don’t like her with Scott, but the fact is that they are together, yet we haven’t really seen any intimate dialogue between them. Overall, I would love more of Jean’s personal stuff, outside of her ”job” as an X-Man.
