Edit: actually i mean Dark Star
Jhin Is popular so blah blah.
But shaco? Karma?? Din't she got a skin months ago? How are these improbable champs getting a dark star xerath skin? He's been waiting 4 years and more, and he got a marvelous fan made dark star concept made since the debut of the skinline.
Edit 2: to see the good in this, by giving a skin to shaco, it looks like riot is tackling the "4yrs wait" club, so xerath shouldn't be far off. hopefully.
