American Expat living in China, would like some help optimizing the game

Hey there, US native living in China for a year, I am wondering if it is still possible for me to play the game without major lag spikes or ping using a net-booster along with my VPN?

Back home I enjoyed doing a lot of RBGs and arenas, something that requires a decent connection to do, I am wondering if that is still an option for me living in China, I do live in Shenzhen so I am near Hong Kong if that helps.

I am asking on the Illidan forums because technical support was rather unhelpful and I am told that this realm has the highest proportion of refugees from the Chinese server shutdowns from the mainland.

not sure if its true but I recently heard wow is going global in 10.5 but im not sure if thats true.
