The X-Men have been somewhat isolated since the "Dawn of X" era began, with the team largely refocusing on Krakoa's interests above all else. But in the aftermath of X of Swords, it looks like one major mutant leader is ready for the team to be heroes again.
The X-Men are becoming bigger heroes again throughout the entire Marvel Universe, thanks to the leadership of Cyclops.
Since the formation of Krakoa, the X-Men have been less of a proactive superhero team and much more of a targeted strike force. Certain branches of the mutant nation have been focusing on specific missions and targets, taking down certain enemies and dedicating themselves to mutant life above all else. While this has bolstered their numbers and installed a genuine sense of community onto the mutant nation, it's also come with ruffling the feathers of other heroes and their teams. The Fantastic Four, Black Panther, and Deadpool all have been shunned or angered in some form by the X-Men, leaving the mutant heroes somewhat isolated in the hero community.
However, it looks like Cyclops is leading the charge against that ideology and bringing the X-Men back to a more heroic ideal. During the climax of X of Swords, he argued as much in front of the Quiet Council. Despite their impulse to remain on Krakoa and instead leave their members in Otherworld to their fate, Cyclops instead used the Peak and Magik's teleportation abilities to lead an entire army of X-Men into battle. While it may not have been formally sanctioned by the mutant government and cost Jean Grey her spot on the Quiet Council, Cyclops made the point that it was still a heroic act that needed to be carried out. In the end, this ended up being the final step the heroes needed to defeat Arkako's forces and ensure peace between the two armies.
These changes seem to be extending to how the X-Men act within the greater Marvel Universe as well. In Outlawed, Cyclops and Dust arrive on the scene of a brewing battle between the remaining Champions and the forces of C.R.A.D.L.E. -- offering the team asylum on Krakoa despite their non-mutant status. In Avengers, the X-Men are reaching out to help the titular team contend with the return of the Phoenix Force and what that means for the future of the Earth. And in King in Black, the X-Men provide reinforcements for the heroes of New York City, arriving on the scene to help combat the Symbiote armies of Knull as he descends onto the planet.
All of this suggests that the X-Men are recognizing that they can't just isolate themselves from their allies, even when they've become as powerful and singular in motive as they have. Cyclops is leading the charge, with his role as one of the elder statesmen and leaders of the X-Men giving him a real sense of authority over the collected mutant masses. The fact that he's also a Great Captain of Krakoa instead of a member of the Quiet Council allows him to be far more open-ended with the missions he assigns, allowing him to bring the X-Men further back into a heroic light. It even seems to affect his allies, with Charles Xavier leading the X-Men from afar during the opening salvo in King in Black.
It's nice to see the X-Men resuming their heroic duties to the world, especially with Cyclops -- who spent much of the previous decade in a more revolutionary and controversial state -- at the forefront. It's a refreshing change of pace for the X-Men to return to their heroic roots.
