What a lot of people are struggling with is the fact that Niantic keep moving the goalposts with each Shiny release. It feels like every time a shiny is released something has changed compared to the last. They are way to common, or way to rare or only being obtainable in raids, or only being shiny during specific dates, going missing, the list goes on and this really fueling a lot of anger regarding shiny Pokemon.

What also doesn't help is the fact that we really have not had any "new" content in months now and "Shiny Hunting" has become the main goal for a lot of the player base when it probably shouldn't.

Is it just me? It really doesn't feel like it's just me a lot of people are seemingly getting more and more frustrated with the game with each Shiny release.

I couldn't agree more mate - perfect summary of the current situation. Niantic need to do events with pokemon rarely having legacy moves, or status effect moves etc.
