Was at Time Walker's trading post during Blizzcon. $40 for real live loot boxes, with the chance to have tcg mounts as well as other shovelware crap from the last few Blizzcons. I bought 2, and joked that "Im part of the problem, lol!" Live from day 2, and the line for this attraction is on both walls of the North hall, floor 2, and there's a pissed off guy with a line at capacity flag. My jaw hit the floor.
Give it a year at most. Loot boxes will be a thing in Blizavision games.
Edit: I JUST GOT 3 MORE
