And also, this seems to me like it's going to mess up the game's mechanics for the people who buy premium consecutively for a long period of time. Eventually, they will have a high rank from the boosted xp, but the amount of crystals they earn in that time will not be enough, and they won't have enough m3's. 50% more crystals is not nearly as powerful as 50% more xp.

Yeah, I didn't realize that. And now that I think about it if people buy premium they are probably just going to buy crystals and buy regular m3's lol

OP is all I can say....if they buy premium they will buy crystals, enabling them to buy XT items (M3's) far too early. End of story. Sad that TO has gone this direction. Can't wait for the new Tanki X to come out...maybe not going to be a buyer's paradise.
