But why? Well, it has everything to do with making Battlelog the best experience for gamers possible. The service is now completely web-based, which unfortunately rules out the possibility of supporting current-gen gaming hardware.
Battlelog is powered by the web, and that has a lot of implications. There are a lot of different things you can do, things you can do faster, rather than building stuff in native code.
It's going to be a lot easier for us to actually update things from the in-game Battlelog than would otherwise be the case. You'd have to do patches normally; here we can actually do things almost by the flick of a finger.
