A bit of info about the ELC
Some people wondered why they didn’t receive the pre-purchase offer, despite being Premium Account users and with battles on it. It seems that a small percentage of those players weren’t included in the campaign. Sadly, we cannot change the campaign retroactively now. The good news however is that the same offers will appear in the store in about a week, with identical pricing as in the pre-order. We know that it’s sad that you can’t drive the tank you were looking forward to, we’re sorry! But in one week it will be there!
