Wow I am kind of annoyed with this game now. I was expecting after Mastering Knight and Monk I would get some new class (Which I think is Geomancer) and Geomancer has been complete shit, I have hated slugging through it but I wanted to see what would come next so after taking the time to Master Knight/Monk/Geomancer what comes next? I was expecting Samurai or Dragoon but nothing, do I have to take the extra waste of time to slug my way through the Archer/Thief classes that I don't really want to do with this character just to get the next stage up in my powerhouse job tree?
hahaha, man, didn't you read those little graphs telling you which classes lead to which? geomancer is pretty shitty and i don't think i ever really fucked with it, because it just didn't seem worth the effort it took to make it not suck. you need it at level 2 to get ninja, which i did, and at level 4 to get dancer, which i definitely didn't do. i don't even know why you'd think you have to master the classes. samurai requires knight/monk/lancer to be no higher than level 4, and lancer itself only requires you get thief to level 3, and archer to level 2, which takes all of half an hour. i think the same goes for ninja. you don't actually need to go into the final job of the tree it's related to, just the second final job, and then you have to go into the other tree and get its final job to level 2 or 3 or something minor.
i just went to
http://chaos2.org/ff/fft/jobs.shtml and chose the classes i wanted to be, and figured out what i had to do to get there, and did the bare minimum. no mastering necessary!
