I think it's pretty clear the current creative team does not want Emma on the X-Men and don't see her as a valuable member to the current team dynamics.
My problem with this is that it's because they think she's too much of a villain, even when she was a hero. But let's not forget both Cyclops and Wolverine were preemptively killing other people... yet they get to be on the X-Men again and look like good guys, yet Emma can't. Totally unfair.
I think the trust the X-Men has for Emma has been ruined, thanks to IvX and recent events. It's been sabotaged by writing, and they're turning her into another Mystique. They've thrown her under the bus, so that the other X-Men who were complicit in the X-Men's formerly "villainous" ways or whatever get off free, including Cyclops' predictable road to redemption.
I don't think we'll ever see Emma and Jean team up again either. We only got that one ghost story that the real Jean possibly doesn't remember. Yet they put Cyclops and Wolverine immediately back together. It's stupid and sexist they can't portray a complicated rivalry between two female characters and avoid the issue altogether and can't do the same for the male characters.
If anyone hasn't noticed, all I do is post negativity on here. I'm very aware of it. LOL. I really need to spend less time putting such negative energy into things. I should probably take a break from comics again. I took a looong break that included when IvX came out, and it was blissful!
