Oh yeah forgot that Hand of Edward the Odd ( http://www.wowhead.com/?item=2243 ) got nerfed from change on hit next spell instant cast to next spell cast in half time :'(
Actually it is that way on live now--the tooltip is just wrong. They used the same proc for the meta gem (chance on spellcast to make the next spell instant) and when they changed it HoEtO also changed. Both procced the "focus" buff.
I'm guessing it was unintended but that they decided it might as well stay... can't let those pre-bc items remain useful, now!
