The biggest issue isn't the removal of PokeVision, it's the complete silence from Niantic like the article stated. We have gotten no explanation on how to properly track Pokemon or how to effectively catch Pokemon (like does curving or getting a "Nice!" actually help). Even their statement last night was vague and unsatisfying. Essentially they removed the nearby feature because it was broken, but never explained how it worked, why it was broken, or what new systems they may be implementing. They keep the players in the dark about the game's features, but still expect the user base to support the game. Even the main Pokemon games still demonstrate how to catch a damn Pokemon, you would expect this game to at least explain the very basics. I'm still playing the game, but the enthusiasm and fun I had at first is dwindling.
