– removed the Mountain Pass encounter
移除了胜利之门的遭遇战模式 

– WT E-100 was not touched
百运没有变动

– tier 8 and 9 tank destroyers recieved some nerfs, specifically the gun traverse (turret rotation) from 24 to 18, tier 8 recieved a nerf on hull turnrate (42 to 38), same goes to tier 9 (40 to 36)
8级和9级的TD（新线的）被Nerf了，尤其是炮管的转速（炮塔转速）从24下调到了18,8级的车身转速被从42砍到了38,⑨级也被砍了（从40到36）

– the “visual model changes” are actually just some shadows on the hull, absolutely nothing visible at first glance
上述的“视觉模型改动”只是车身上部分阴影的改动， 目测装甲没有改动

From Storm’s answers regarding this topic:
Storm对于这个话题的回答： 

– there will be no separate rework specifically for BIA, it will only happen if the perks are globally reworked
不会有专门针对基友连的改动，（改动）只会发生在全体技能一起改动的情况下

– Storm states the global rework of perks and skills might happen: he’ll revise the old ones, think of new ones, but this will not happen anytime soon, there are other more important issues in game
Storm表示全体技能的改动有可能发生：他会先审查一下所有旧的技能，然后想一些新的技能出来，但是最近肯定不会有，游戏中还有更加重要的问题要处理

– Storm states that the current WT E-100 will be the same case as the FV215 183, where everyone whined that it’s overpowered and in the end it turned out not to be the case
Storm表示现在百运的情况和当初FV215 183的状况差不多，就是在测试服的时候所有人都觉得这车特别的OP，但是最后发现并没有这个问题

– T-44-85 will not be released in 8.9 apparently, devs decided to rebalance it (buff it) so it’s playable, they are discussing what to buff, but of course it’s about the penetration
T-44-85不会出现在8.9中了，开发团队决定对它进行重新平衡（Buff它），让它更具有可玩性，他们正在讨论要Buff什么，不过不出意外的话肯定是穿深

– Storm confirms the encounter on Mountain Pass will be disabled
Storm确认了胜利之门的遭遇战会被移除掉

– some buildings on the new map are not destructible while they should be, it’ll be fixed
新地图的部分建筑在理应被摧毁的时候没有被摧毁，这是个BUG，未来会修复。
