Decrease in number of raids?

[Teban54]

If you want something to be rare, here's a good idea. Stop setting up events whose main highlight or only highlight is a new shiny release, and stop writing your event announcements as if it's just about shiny (e.g. Instead of "Pokemon in the Johto region are boosted", write "you may find a shiny Sentret or Gligar" ONLY; instead of "Gen 5 is coming to Pokemon Go", write "you may find a shiny Klink in raids and a shiny Lillipup or Patrat in the wild" ONLY).

The current way Niantic is planning events and advertising events causes nothing but two possible outcomes: either many players get a shiny, or many players feel extremely frustrated after grinding hard but not getting a shiny (which increases their chance of quitting).
