Tankers,

The World of Tanks team is working hard to bring you the best game experience possible. In recent months we have also noticed a heavy pressure of the World of Tanks community, highlighting a very serious issue. With the introduction of the Ratte, this issue will only become worse over time.

We are aware that in the current situation the Soviet tech tree is underpowered and most of the vehicles obtainable in this tech tree are unplayable. Recognizing the requests of the community we are proud to present the following changes:

In the medium tank line you will be able to research the T-62, T-72 and T-90 tanks which will be added after the tier IX T-54.

In the first heavy tank line (IS-7 line) you will be able to obtain the Object 277, Object 279 and Object 195.

In the second heavy tank line (IS-4 line) you will be able to obtain the Object 430, T-64 and the Hammer.

In the TD line you will be able to get the Taran tank destroyer.

We will also add two SPG lines after the tier VIII SPG. The first line will consist of the Pion and the Kondensator while the second line will allow you to research the Akatsiya and Koalitsiya.

We hope that you, our community, will be happy to see these changes bringing balance to all the tech trees. We hope to implement these balancing changes before the French tech tree extension.

Stay tuned for more information!

　　坦克手们：

　　坦克世界研发团队正在努力为您带来最好的游戏体验。在最近几个月中，我们也注意到坦克世界突出了一个非常严重的问题。随着Ratte的引进，这个问题随着时间的推移只会变得更糟。

　　我们都知道，在当前形势下，苏联的科技树不够给力。认识到这个现状，我们自豪地介绍以下的变化：

　　中型坦克线，你将能在IX的T-54后研究更先进的的T-62，T-72和T-90坦克。

　　重型坦克一线（IS-7线），你将能够升级为工程277、工程279和工程195。

　　在重型坦克二线（IS-4线），你将能够升级为工程430、T-64和Hammer（悍马？！）。

　　在TD线，你将能得到Taran（塔兰坦克歼击车）。

　　我们也将增加两条线路的8级SPG。将包括Pion（介子）和Kondensator的一线，还有可研发Akatsiya和Koalitsiya二线的自行火炮。

　　我们希望你会很高兴看到这些变化，所有的高科技树推动游戏平衡。我们希望实现这些平衡的变化之前，法国的科技树也将延伸。

　　欧服官方虽然是在3月31日发布的新闻，但不排除是愚人节的整蛊消息，宁可信其无，也不可信其有啊！但要是真有就好了……到底是真的还是假的！
