What the heck?! Then how come Jubilee currently is a main character in X-Men '92, was just stated to be a player in X-Men vs Inhumans later this year, and makes guest appearances currently in titles all around the marvel universe like: old man Logan, a-Force, squirrel girl... And is joining Hellcat's solo title in October as the solicits say, "everyone's favorite teenage mutant vampire..."? She's not just relegated to X-Men titles... She gets appearances in other titles, action figures, t-shirts, collectible pins/statues/etc... All in the past few years.
During last year's secret wars event... There were at least three different versions of Jubilee running around. During Age of X a few years ago, there was a present version as well as a future version of Jubes... The future one was the leader of the X-Men... Both got heavy focus.
I don't see how that makes her not relevant.
