Dude. I bought Khitai just a couple of months ago. Regardless of what you say, I clearly remember the details 100%. I was torn between starting a new account and saving 15$ on subscription time, or continuing my old one from 2008 which had a fair bit of offline lvls and veteran tokens.
It's not like it matters, since pretty much everyone buys the expac after they've already had an account and characters for a while and are probably unwilling to start over, and most people buy in the store rather than from an online reseller, but facts are facts.
