为确保副本的稳定性，一个副本平衡机制已经开始实施，它会限制一个服务器上可以创建的副本总数。在此改动之前，我们注意到副本中的一些问题很严重会大大降低副本的流畅度，甚至还有可能导致全面的崩溃。

此次修改将会在开启新的副本前进行负荷检查以限制副本数量。这样可以减少一些副本的创建，用户将会收到如下信息：“无法开启额外副本。请稍候再试。”我们觉得让玩家等待一段时间才能创建新副本要比让所有在副本的玩家遭受糟糕的游戏体验要好得多。

我们会持续关注服务器的状况，并收集数据进行进一步优化。最终目标是可以移除这一限制。

To ensure stable and positive performance in raid and dungeon instances, an instance performance balancing feature was implemented which limits the total number of instances that can be created on a realm. Prior to this change, we were seeing serious issues in instances which greatly degraded instance performance, and in some cases, caused them to crash entirely.

This update instituted a load check that limited opening of additional instances. This will result in throttling of some instance creation where users receive the following message: "Additional instances could not be launched. Please, try again later." Ultimately, we felt that some wait time for players attempting to create a new instance was better than causing bad performance for all players in instances.

We are continually monitoring the realms affected by this, and use the data we gather to implement further optimisations. Our ultimate goal is to work toward the removal of the limit.
