Badge 4s located anywhere yet?

Besides the mission pass. Tempted to max it out and get the lower tier 14 until next weeks mission. The other are annoying to get since you need so many stones and nowhere near enough weapon badges.

Main Mission gives 100 when you get the "Positively Insatiable" title (lvl 75 in two classes then talking to Lacheisis at the Title Counter). Other than that, not at the moment.
