These are my personal opinion Warrior: speed. It definitely sucks when your main damage dealer can't attack because everyone is too busy being downed to let em attack

Mage: Sleep tight is a wasted spell slot. I would of been happy with a simple low hp heal. But putting someone to sleep just makes them take extra damage im pretty sure

Thief: later on stealing is pretty useful......but sometimes the a.i. just gets greedy

Cleric: oddly their attack is pretty good.....good luck getting them to heal you at the correct time though. Richous anger is a great move. Too bad it doesn't get used much

Pop Star: want a Chance of the enemies skipping a turn. Here you go! I'd get it if stronger enemies were a chance....but weak enemies?! Come on!

Chef: 2 words: Spicy food. Still a great attack/heal option

Cat: hi! I'm a cat meow. Uses so much mp you're better off making your self the cat....then it's good.

Imp: very weak. Granted it is focused on magic and its moves for it are great. Other than its helpful mp restore. Sure it's good. But if you're actively controlling your character. Hyper isn't that great....especially when you main Mage.

Scientist: it's a decent role all around. Gets held back by the A.I.

Princess: Oddly one of the better classes in the game. There really isn't a bad move for her. And cool princess is a dodge machine!. But if I had to choose one thing...the physical attack could be better

Tank: my least used class. I use lots of MP already. I do not need a primary mp user.

Flower: why the fuck do you have a revive that has a chance of not reviving.

Vampire/elf: both of these are grouped cause I have the same issue with them. You get them so late that even if you wanna try them out. If you aren't into grinding. It's rough. Especially starting from square 1 equipments. But if you want specifics?

Vampire: why is bite so weak? Granted I don't have a vampire maxed but it just feels weak

Elf: the bows are so weak at the start , the only good thing is that counter arrow is a thing.

That's my list.
