I forget, since the series was so bad, but did she appear in X-Corp? I feel like she at least was on a phone call with Jamie.
Layla was only mildly interesting when she knew things. Her actual mutant powers aren't very interesting. No one is really clamoring for Elixir to have more stories.
That said, being 'ignored' is not the worst thing in the world. Madelyne is currently not being ignored for another rehash of Inferno. Turning Moira into a mustache turning villain is another example of the perils of not being ignored.
