Having checked on live the following single group heroic zones have the old "18h" timer Crystalline Breaks Obelisk of Ankhul Najena's Hollow Tower The Shipyard Cove (Tradeskill Instance, not sure if this is intended, but the other 3 have been changed to 90mins) the Following zones are single group heroic, but had timers less than "18h" before the patch: The Hidden Cache (currently 12h 30 mins) Court of Korucust (currently 3 hours) That is all I can find across my main characters; feel free to add to this list.

OoA is just too far away from anything else to matter or include in a sensible zone rotation. Unless you camped 9 alts at the door maybe? and /camp to a different toon every 10 mins? But then you can do that with CoA, DF. CoA, you can pretty much ignore all mobs on the way to the plat chest.
The tradeskill instances are supposed to be daily, so the 18h lockout should apply. The bug seems to be the other way around.

As a warlock I then just port out to stonebrunt and do library and research halls to the plat chests and key mobs, port to commonlands, do befallens. The short flight to ooa alone makes it not worth it.
