You want to do run Cazic Thule (the instance) before Permafrost.

Cazic Thule -> Permafrost -> SoS (something of Scaleborne) -> Mines of Meldrath -> Ak'anon -> Ak'anon instance (this is a hard instance, be careful) -> Temple of Seeing (or whatever that group instance is) -> Mistmoore Catacombs -> Castle Mistmoore -> Nizehrlekhfsifh (some instance that people say is hard, but it really isn't).

I know I'm missing an instance
