Status update as of 25-Feb-2015 11:44UTC
Even though the patch size was relatively small, there were a significant number of changes made. At this time, it appears we will have an internal test build available later today. It will probably be tomorrow before a [Testing] release can be made available.
We've also observed that the WoWclient is using an excessive amount of CPU, and producing low frame rates for what our boxes are capable (with no Honorbuddy involved). We hope there will be a hotfix to address this significant WoWclient performance issue.
