Finally managed to fix this whole save state fiasco with Etrian Odyssey 3, but I had to restart the game. I'm at the point where I can make my team. I'm kind of unsure what to do now. To the people who've played, what are your opinions on all the classes?
Edit: Ended up trading it back to the friend and they gave me the first Etrian Odyssey. It was much easier to choose a team this time around. My team consists of a Medic named Yukiko, an Alchemist named Lulu, a Survivalist named Aigis, a Protector named Fang, and a Dark Hunter named Paine. All lolis, of course.
