Pokemon Go's New Lycanroc Evolution Sparks Player Frustration

Niantic's decision to limit Dusk Form Lycanroc evolution to new Rockruff caught during the Lustrous Odyssey event draws criticism.

Pokemon Go's new Lustrous Odyssey event introduces the Dusk Form Lycanroc, but players are frustrated with the evolution requirements.
Only Rockruff caught during the event have a chance to evolve into the new form, and even then, the evolution is randomized.
Existing Rockruff, including those with perfect IV stats or Shiny versions, cannot evolve into the Dusk Form Lycanroc.
Players criticize Niantic for the decision, viewing it as a money grab as they may need to spend more on new Rockruff.
Some players defend the mechanic, saying it aligns with the mainline games, but others argue that the original games are a single purchase, while Pokemon Go incentivizes constant spending.
