Whats worse is Celestia is forcing Luna to do that too.
Luna WANTED to help like in Season 3 when Sombra came back but she wouldn't let her do so because its a "test" for Twilight.
Most likely all the times they purposely choose to not help, deep down Luna is pissed Celestia made her stay out of it.
Like all of those times, Celestia forced Luna to stay out of it.
Celestia doesn't realize that will mess up Luna's already damaged reputation even further. Celestia's reputation might handle, but Luna's definitely won't.
