I definitely wouldn't mind this. Back when I was active on Mabinogi, the last year or so of my playtime they changed the launcher's background each time there was a new update, so we'd have gorgeously illustrated images of, say, Hamlet, or a nighttime island vista, or so on.

@Enkidoh: We're talking about the title screen you see immediately after you log in, not the box. The screen would then be something like Final Fantasy XIV: A Realm Reborn with the current patch logo (let's say 2.3 for argument's sake) and then below, something like 2.3 ~ Guardians of Eorzea.
