Trainers, thank you for your feedback on EX Raid Battles. We're working to improve the invitation system based on what we heard from you.

Who..fucking..cares? Where’s the traditional battle/trade system that everyone has been begging for asshole?
I’ve blogged a lot about Pokémon Go, and I’ve felt disappointed by how the game ended up. They had the lightning in a bottle but I feel wasted it.
It did wasted that opportunity. Believe me, had it done the traditional battle/trade system like in the main games in Go, it would’ve been super popular bar none and really get a lot more fans into the main series on consoles which would’ve helped the 3DS/Switch a lot more. But fuck it. Niantic is the pinnacle of “incompetence” and will never give a fuck to truly improve and change the game. They had the chance to become a household name but they fucked it up within WEEKS.
It’s sad to think of what could’ve been. Hopefully Nintendo sees the power of Pokémon and puts other variants in the hands of non-Niantic companies
They can still take the project and have someone else do it.
