Perma MC

if you MC someone in a BG and they die while mind controlled they will become permanently mindcontrolled and unable to resurrect. Will hold until that player quits the game and logs back in.

will probably get fixed to next patch, have fun meanwhile :-P

yes and sometimes also the corpse is recovered in a strange state where the user is a half ghost which cant cast any action but is able to walk over the BG and can be seen by all. In this case just doing an /afk will work to resurrect.

happened to me as well once, I wasn't mind controlled after dying though, my ghost was just following the priest and after that one died it "switched" to the next enemy and so on.

\n'd out of the game, reconnected and I was in control again.

Works for example in Cenarion Hold, too. MC someone and let him killed by the Guards.. works with Mind Control Cap, too. He looses 10% Durability AND has to relogg :P
