When did you quit playing? They've kept working on it really steadily, it's MUCH better than it was at launch.
I quit right before raids came out, and from everything I've heard it's still worse than it was at launch. I don't really want to derail this thread but fuck it, it only has a few posts in a month.
Here's the trailer for PoGo, I remember being super pumped for it when it released.
Watch that and tell me whether Niantic delivered on that trailer with today's PoGo (ignoring the notional AR stuff that we just don't have the tech for yet).
At release we really only had the hunting / capturing Pokemon feature in and it was remarkably like the trailer. People were running all over looking for Pokemon. Then a combination of people realizing how effective lures were + niantic destroying the ability to hunt pokemon turned it into a game where people sat on their ass spending $$$ to win.
I didn't get into raiding, but the raid pass mechanic reaffirmed my decision to not play. Niantic had the option of creating a global hit, but instead they seemed to just chase their cash shop.
If I'm wrong and Niantic actually did reform a bit and the game is like that trailer, let me know.
Which is why I think it's up to Nintendo to create Pokemon Go II, since unlike Niantic they actually give a shit about their brand.
