Today I was leveling at Garlaige Citadel. There wasn't much to choose from when you make a party, so we ended up having a party of THREE thiefs, a warrior, red mage and white mage.
It surprised me how well it worked. One thf had war sub job and others had ninja. It worked fine when thf with war sub pulled with provoke, ran to camp and provoked again, so that one thf could sneak attack + trick attack behind warrior. After that warrior provokes and I sneak+trick behind voking thief. After I sa+ta, thief infornt of me gets behind me and does the same. At this point, warrior has enough hate so we ALL thiefs can make a line, and the one who has done sa+ta combo moves in the lead of that line. It looked weird and funny and it worked. It was definately a good experience and I got almost two levels in that party 'till I had to logout.
So, this topic is about parties that are far from ideal on paper, but somehow you just could make it work much better than the odds are.
