As long as they've managed to snuff out twinking and eliminate the horrible latency, I have no issues with this. Matchmaking by "soul history" and dedicated servers are both intended to address this. Hopefully they work.
I was wondering what the hell that thing was!. I was on the rafters in Anor Londo when I saw what looked like a Black Phantom standing on the ledge under the Gwynevere statue. I couldn't really make it out too well from that distance, but I thought it appeared rather crab-like and unlike anything I was familiar with in the game. Once I got a little closer it pulled aggro and walked right off the ledge to its death before I could figure out what the hell happened.
Had no idea these were a thing.
EDIT: After reading about them, I realized that I actually have heard of these things. I remember around launch hearing about the items you drop being moved on to other online players. I guess they were so rare that I just assumed they were never actually implemented and I forgot about them. This is the sort of weird shit @patrickklepek would really appreciate about this game.
