The test server is up and running right now, you should download the client for it and then give one or two of the premium tanks a try. that is what i did and i found that i made the best credits with the JT8.8 though once i got used to the SP i do make decent credits on it.
I rate the battled due to the damage that i have done in them.
here is an ok battle in the SP
