Popped in Final Fantasy Tactics yesterday, played like 12 hours straight!
I'm at the Golgorand Execution Site right now. My party consists of a Summoner, Oracle, Lancer (Ramza), Monk and a Geomancer. They are all around lvl 14.
(SPOILER)This playthrough I'm going 100% I think. I'm going to do all the side quests including propositions and Midlight Deep.
I have not done those 2 side-quests ever. The Midlight Deep without a guide is just impossible. I once spent 2 hours on the second level and I never found a way down.

The propositions just feel pointless, but I haven't done them yet so, why not try?

I believe that I will max out all the classes before the Midlight, but that's going to be annoying.

EDIT: Wow, Summoner learned Leviathan and it did like 270 damage on Gaf. That reminds me that I should steal the Blood Sword first. So I'll restart...
