On my Alliance DK, I ran into Org to get my fishing and RFC achievements and while going into RFC, I noticed an odd DK glitch:
I was killed by the guards just outside the instance, but with the help of Shadow of Death, I was able to limp my ghoulish self into the instance. Once the splash screen resolved, I was back to my non-ghoulish self and at full health, even though there was a red note on the screen saying "You are dead".
Just thought that this was odd so had to share it with you all.
