Where do I sign up to test those nudges?
As I said, they're just the Rageball nudges. Anyone can join rageball and play around with the nudges there. Rageball isn't battle/siege though, so we're testing on those servers ourselves, first. Unlike most things, where beta servers get patched with this first and then if we like where it's at it gets put on the other servers, this doesn't actually require a server patch(at least not yet). Urist would still have to do a few things for it to be ready though, so just because
I said it doesn't require a server patch, doesn't mean other work isn't in need of being done(it's also true that things could change that require a server patch for it.)
I'm just a mere item balancer, I don't do any coding. But there's one thing I can say; ETA: December 2010.
