FIGHTERS are good because their large amounts of health and armour give them a good survival rate and prevents them for having a monster-induced sleep all the time.besides it's great to have a tank.
RANGERS can have nearly as much AC as fighters and due to not needing mana are almost the ultimate solo class because of their hit-and-run qualities.
NATURE MAGES are generally too weak to make good soloers but their heals,buffs and summons can make them work if you patience.
COMBAT MAGES can be very powerful but the combination of spells that can go through walls and/or hit multiple foes,powers like Corrosive Eruption,and their very low health mean you have to use a lot of tactics to make them work.
Hope I helped in some way
