They know about the bugs. The thing is, they’ve screwed so many things so horribly that they’re having trouble identifying what exactly is causing the bug, let alone how to fix it. Regarding hunters, they changed the batching queue screw up that borked hunters but they haven’t figured out how to fix other bugs CAUSED BY THEIR BATCHING.
There are other reports about it taking too long to drop combat, or having combat re-activated because your pet is getting attacked, and we’re still looking at those issues. We’re tracking a couple of leads there, but we haven’t got this bug in our sights yet, so it may take a bit more time to figure out what’s really going on here. - Pazorax, Wow Dev
Here’s how they could fix it: Get rid of batching/leeway until they have a freaking clue.
