Hello warriors,
大家嚎，

here’s a surprising turn of events from one of Wargaming’s RU staffmembers (the thread where it was got deleted but the North Google cache remembers). Since there is no debunking from Storm available (he usually posts very quickly if such info is false), we have to assume it’s the truth.
WGRU的工作人员来了一次惊天大逆转（帖子本身已经删掉了，但是Google的缓存中留下了证据）。鉴于Storm那边没有任何反驳的消息传出（他在这种帖子的信息错误时会很快的发一个辟谣贴），所以我们就得先假设这帖子里面说的都是实话。

There will be no penetration nerf AT ALL, since the tests have shown that it didn’t work. So no changes planned for now (at least summer and autumn will be without changes).
穿深不会被砍了，因为测试结果证明这么改行不通。所以现在暂时没计划在弄出点什么改动（至少这个夏天和秋天，穿深都不会有改动）

Also, Mauschen will not be implemented (it will not be in 9.9 test 2 anymore) because it sucks, devs decided not to put it in.
还有就是小鼠式不会实装（9.9的二测里这车就会消失）因为实在太烂了，开发团队决定不把这车放进游戏里了。
