There is decent evidence that maestro should be 12 hours until Hateplane upgrade, I'll discuss it with the other devs.
Using the same links lists dracholiche as a 1 week spawn until Fearplane is updated, so I did a bit more research on that:

"7 day respawn"
http://www.monkly-business.net/forum...hp/t-8845.html
"Dracoliche, level 53, 7 days, Plane of Fear"
"Dracoliche****, level 53, instant, 7 day respawn, Plane of Fear"
"**** - I'm not sure if Draco respawns on his own, or only when CT respawns the zone when he spawns. "

"Draco spawns once a real-life week. Special Skills: DOT and dragon roar."
http://www.geocities.ws/keylargo60634/pofguide.html
"Cazic and Draco set to one week."
I'm not sure if it will be changed at this point in the timeline, but it's in discussion.
