Training Places For All Jobs [post-BB]

The quests supposedly drop down to 333 requirement, though this was not reflected in Tespia. I believe the monsters mostly become stronger after Big Bang as well.

Cellions at 46 are pretty fantastic if you don't want the hustle and bustle of Kerning Square.
I hear the mixed map past that is pretty good too but I've never tried it.

Mithril Mutae are decent for 8x. They're not much worse than Iron Mutae in my opinion, just significantly lower in demand.

Turns out the 333 only applies to the Victoria Island hunting quests. For some reason everyone was led to believe that the Time Temple quests were also cut to 333.
