Yes, I'm still knee deep in Diablo III and I'm onto season 2 now. I've rocking another witch doctor and so far, am doing pretty good and enjoying playing with my friends. Patch 2.1 was the last great big update, but 2.2 is coming with some much needed new content.
We're talking new Legendary powers, new set pieces, new rift maps, new goblins, and changes to the interface. From what I read, it looks like it's going to be a great update. I'm always up for new items to discover. One small disappointment is that there won't be many class changes, if any. That's OK though, as 2.2 will have plenty of other things to look forward to.
