Feign Death is definitely working on Malygos (thank goodness) now we just have to worry about our crazy warlocks.
Outstanding (bad) Bugs that I've noticed. I don't talk about good ones
-Pets will occasionally change all of their autocast settings.
Workaround: Make a macro with /petautocaston and /petautocastoff listed for all of their skills. One click solution! I don't remember Blizzard mentioning a fix in 3.1.
-Killshot minimum range.
This one really sucks on Thaddius. I think Blizzard is fixing this in 3.1.
-Explosive Shot and Misdirect.
What's happening here now in 3.0.9 is that the threat from debuffing the mob with explosive shot eats a charge, which means there are only two charges now but 3 ticks of explosive shot. That means we still can't pull with it because if, for example, you have 40% crit when you pull, there's a 14.4% chance you will not crit on the first two ticks and crit on the last tick (ignoring boss crit depression) possibly resulting in a bad pull. However, this method works well on misdirecting ranged trash to the tank because if you get really unlucky you can just FD and the tank will at least have 3k+ threat on it.
-Disengage sending you in one direction then "popping" you to a different place.
This usually happens when you are spinning around and use disengage, and it is probably related to latency. You might need to face the same direction for twice your latency to ensure that it doesn't happen. This likely won't ever be fixed.
-Threat from feign death suddenly reappearing when you stand up.
From what I noticed, this will only happen if you were on top of Omen when you FD. In other words you passed the tank but not the pull-aggro threshold. Using FD before even passing the tank seems to fix this problem for me. It might even be working as intended now...
-Feign death not working on city guards anymore
Working as intended?
