Having gathered a lot of your feedback and suggestions from past couple of months, we came to the conclusion that Rampage mode does not meet fully the community's expectations and still requires some work to be done.
Minding the amount of feedback received, as well as the timespan of Rampage battles being available, we now have a lot of credible data to work with and see in which regards the game mode does not perform as well as it should and why it's not as popular as it could have been. As a result, we have decided to pull Rampage battles from the game in the next Update.
While Rampage battles will be removed, the mode introduced many new gameplay features (respawns, multi-team battles, being able to enter a battle with multiple tanks to name but a few). This opened great possibilities for further development of World of Tanks. This means that these features may be reintroduced to the game in the future, in part or in whole, possibly as a vastly improved version of the Rampage battle mode.
The maps Ravaged Capital and Berlin, which are currently Rampage mode exclusives, will be reworked and reintroduced to the game for rotation in Random battles in the future.
The T-22 medium – the main reward for personal missions in Rampage – will remain on the accounts of players who managed to obtain it before the game mode's withdrawal.
However, the tank will undergo rebalancing in the next update, in order to make it perform adequately in Random Battles and to even out its performance in comparison to its Tier X peers.
