Why if i am literally PAYING MONEY for a premium account...

DeviouslyCursed: Fun fact: Back in the day your tanks' average xp used to include the extra xp from prem account. They changed that a very long time ago though. Their month long missions for IS-6 and such also used to include xp from prem account, daily x2, and events such as x5 or weekend xp specials. They changed that after the T34 or the WZ-111. Can't remember which.
