I think some people dont understand the uses of some classes in MMO's.....
Warrior : Main Tanking Class, Will be able to hold off alot of monsters due to high Armour, But will only be able to attack a few monsters at a time. Slow leveling.
Wizard: Fast leveling Due to mass attack spells, can kill mass amounts of enemies fast.
Taoist: Aid with Healing / Statistic boosts, Also able to summon helpful pets, Mid range leveling.
