What happened to it?
Does it share cool down with Combat resses and soul stones now, or does it just not work on boss fights anymore?
Edit:------------------
Don't think i made myself clear.
A couple of days ago we were doing our last ICC 10 and my rocketboost misfired and killed me on Heroic Putricide. What had at that given time used our 1 combat ress. When i tried to Ankh i got a message saying somewhat in the lines of: That action is not possible at the moment. Or something like that atleast.
That leads me to think that it now shares the limited uses of combat resses like soul stone and combat res.
