it not satisfying when you catch a Shiny in Reborb, Rejuvination or Desolation? well Desolation makes sense since you can buy a jy of shiny pain to make your pokemon Shiny, but when the other 2 doesnt it feel satisfying?
And yea the paint makes shinies kinda eh in desolation, but they're still nice to get in Reborn and Rejuv. the higher rate just means you have a half-decent chance of finding a shiny of a pokemon you actually want to use in your team.
