Matchmaking in Call of Duty: Black Ops 2 will no longer be region-based, Treyarch confirmed. Rather, it will be based exclusively on your latency and ping.
The information comesdirectly from Treyarch's Game Design Director David Vonderhaar who told fans via Twitter.
For a while now, Call of Duty multiplayer matchmaking has suffered with constant host migrations and drop outs. Hopefully this change fixes the problem. We'll find out soon enough; Black Ops 2 is set to release on November 13.
