User blog comment:MakeShift/A potential renaming of our wiki/@comment-72.73.35.51-20150122041104

As suggested, Arrowverse. It should make sense to people only casually familiar with the shows, and is a name already used in the fandom. It also sidesteps any issues with needing to change the name further if other shows are added, and also helps conceptually limit the scope of the wiki to the single shared universe. It's all there in one name.
