Well, they improving system compatibility first.
Adding more warden systems and bot prevention in the future.
If they solve the problem with the bots and spammers, it's perfect for me again. Bnet will have and has a bigger community and also european servers than any private realm atm.

I'm really looking forward to it, atm I still prefer private realsm though. Content wise it will surely never be like annihilus, and this is where annihilus shines. But bnet could be a lot of fun again for said reasons. Big way to go though but we can hope .
