Training Places For All Jobs [post-BB]

Do the quests for Time Temple get easier after Big Bang? Wanted to go to Oblivion Guardians before, but stuck on those freaking ice monks because I can't freeze them and they're a pain to do. I should probably party with someone, but too lazy to find people to party with.

I did do the first few parts of the quest together with Flamechocobo though. That was pretty fun.

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.
