I'd have to say that the base is barely alive. I just picked it back up after platinuming Bloodborne, and I haven't seen more than a handful of blue signs and I don't think I've ever been invaded since I started playing again. That said, I'm trying to finally platinum this game on my new PS4 account, and I'm slowly going mad farming for Bladestone. This is a little off-topic, but I'm super-desperate for a Pure Bladestone if anyone can spare one. I even registered to this forum just to bum one off someone. I've been farming for hours and even platinumed Dark Souls I and II between breaks.
