#PokemonGO: “Hello Trainer,Thanks for sharing your feedback about Raid Battles.I am sure you are aware of our previous Community Note, where we made some changes to Pokémon GO that affect your Pokémon effectiveness in battle. Now, you might see an increase in HP of the Raid Bosses that appear in Tier 3,4 & 5 Raid Battles. Previously, Trainers were able to defeat the Raid Bosses alone with their attacking Pokémon. As you may be aware of the fact that, Pokémon GO motive is to bring the Trainers together to defeat the Powerful Raid Boss. This is the main reason why rebalancing is done again. However, now, you might notice an increase in the Stardust for completing the Raid Battles.You can refer to this link for more information: http://bit.ly/2Gb4gcR. However, thanks for the feedback about these changes. Let me inform, most of the changes in Pokémon GO are made based on the feedback received from Trainers worldwide. Hence, we take all the feedback seriously and analyze it to implement on a positive note.Regards,”Just thought I’d share with y’all. via /r/pokemongo http://bit.ly/2Rw3pFH
