Hortus updated the PTR forums with a comprehensive list of known bugs and issues. As it is updated I will repost the new information.

2.4 PTR known issues list.
As the 2.4 patch is still in development there are still issues that need to be resolved. This is a list of issues currently occurring on the 2.4 PTR that we are aware of and working to resolve. There is no need to report these issues here in the forums or via the in-game feedback tool.
