Order of favorite to dislike.
Thieves. They were known for their extreme mobility and high damage. However, after big bang, every class gained mobility and other class gained immense buffs. However, thieves remain one of my favorites.
Archers. Hurricane and snipe is gorgeous. Arrow rain and eruption were great.
Pirate. Rapid fire is gorgeous. Battleship was really fun in the old days too.
Warriors, because they probably lift.
Mages, because they don't lift.
