Over the course of the post-TBCC months a growing mountain of bugs has been accumulating on Classic Era due to different patches meant for either TBCC or SoM. So far most of these bugs are not being addressed and all the patch notes have focused on are very, very small or even inconsequential fixes to Classic Era as can be seen in the Hotfixes post.
It is discouraging not seeing these issues, which were not present pre-TBCC, get proper attention and even worse not having any kind of feedback from Blizzard on the matter.
So, what is the timeline, if any, on Classic Era bug fixes? If there is no timeline and there are no plans on allocating development resources for these fixes then that is also good to know since you know what to expect.
