It still works on mine...
What's your server/battlegroup?We all had a disconnect and World Server was down for a few secs, when we relogged someone in my guild said: "blizz probably hotfixed cast while moving", and so I tried it, didn't work, tried bout 20 times (almost died lol). Usually It works for bout 7/10 times. =/ I'm not telling you my server but it's on EU.Just to bump this thread, It hasnt been hotfixed as of this post time xD
