I remember watching a GDC talk of JAM (https://www.gdcvault.com/play/1018184/Network-Serialization-...), which was Blizzard's solution to network serialization for WoW back in 2004. The talk even had performance comparisons against protobuf and it seemed like a decent alternative that worked well for them. Was this new alternative an extension of JAM, or a full rewrite? I know they have millions of players monthly, but I can't imagine saving a bit on bandwidth could have warranted a full rewrite, especially when the majority of their traffic is from their own datacenters.
