Joining the X-Men also means refusing the future Mystique wants for her. Mystique helped raise her and still cares about her, but Rogue is making a choice to stay with people Mystique considers enemies. That's harder than simply changing a costume. Rogue has family ties to the other side, and those ties don't disappear when she accepts Xavier's help. Dazzler gives you another version of the problem. Rogue fought her before they were teammates, so Alison has plenty of reasons to be angry about working beside her. They have to get past that history through what they actually do together. Over time Rogue becomes somebody the X-Men depend on. She does the dangerous work with them, stays through the fights and participates in their sacrifice in Dallas. By the Australian period, she's been with this team through enough that the original question of whether she belongs has a very different answer. They have survived a lot together.
