Our programmers and QA analysts are working on this. There are actually a few unique targeting issues which are all documented and being investigated independently, as they're technically unrelated.If it was a bug that somehow benefited players it'd have been hotfixed immediately yet here we are 3 weeks later without a word on an ETA for a fix for it.
It has very little to do with bug priorities, or our willingness to fix what you think we think isn't a big deal. Each bug entered into the system is a unique case and requires any number of verification methods. The process for properly identifying and addressing a bug is no more or less important depending on the type/severity of the bug.
It's also worth keeping in mind that some bugs can be addressed via a hotfix fairly easily, while others cannot be fixed without releasing a client patch. And no matter how minor the patch, building and releasing it globally is still a major logistical undertaking.
The issue specifically with targeting dead targets will require a client-side patch to address.
Perhaps you can pull some of the real devs and analysts from working on "THE NEXT BIG THING" for a few weeks to put this bug riddled boring expansion back in order? The state of the game right now and the sheer amount of crap getting past QA is completely unacceptable.
