You are absolute right, I am so proud to be an X-Men fans because there, you don't have to worry if a writer try to wipe out the history of the legacy of Mutants. Every mutants from different generation are all living under the same roof at Krakoa.
In the 80's, you have Chris Claremont as the writer for the X-Men.
in the 90's, Jim lee is the artist for the run along with differen writers.
In the 2000's , Joss Whedon launched his "ASTONISHING X-MEN".
In the 2010's, Brian Bendis also write several X-books despite polarized reception.
And lastly, Jonathan Hickman is the " HEAD OF X" meaning he in charge of making plans with the other X-books.
There is a reason why X-Men fanbase have grow stronger every years.
