Same. I play a ton and then realize there's no real point. Need another xpac with higher level cap imo. Each time they tease with this new content I get excited, but realize it's just a carrot.
This does sound like a great patch though. Man, if you didn't play it at all and started the game fresh now, the bang for your buck would be fantastic.
Also gotta hand it to Blizz, putting the kind of support into this that we only dream other titles had. The initial purchase and xpac has been a heck of a value.
