Advantages: Skill scatter makes them excellent hunters and plvlers. Good for making money. Ability to fly speeds up travels u can safely fly around monsters and helps a lot when fighting trojans and warriors that are born to crawl. Its also harder to hit a flying target. Archer armors have high natural magic defense, even higher than taoists. Even if their defense is low with good coat and hat they are not that easy to kill by trojans or warriors and monsters. Good archer is easy to lvl.

Disadvantages: Cant heal themselves. Arrows cost much. They have lowest hit points and low defense so can be easily killed in one hit by trojans and sometimes warriors of same lvl. So you wont even have a chance to run. Even if they are fast their attack is very weak. Bow is 2 handed weapon so you can have less gems than trojans or warriors. When + ing bows the bonus is so pathetic that it doesn't make it worth to + it much. Its not that easy to lvl archer as you need to find a place with lots of monsters and its boring (for me personal). You scatter, scatter, scatter, and the monsters still wont die as your damage is really poor.

There is a question what archer should use cap or earrings. Most of people choose earrings as fire taos are the greatest enemy of archers and they say that that some defense of a cap will still wont save you from trojans. But if you have earrings even poor trojan can kill you in one hit. Its for you to choose.

Trojans.

Advantages. Trojans are born to kill. After lvl 40 they can use 2 weapons. Even if second weapon don't give as much attack as first one it also gives agility and additional place for gems. They have very high hp. Combined with high defense they are hard to kill by anyone. They also have spiritual healing so don't need so many pots. Skill Hercules helps against annoying taos and archers that are jumping around you. Trojans armors have highest defense (from lvl 70 to 110 for sure. 120 warrior armor has more def. Don't know about the lower ones). Coronets look better than helms as you don't see them at all (again my personal opinion). Even skill cyclone is not very good for lvling its really great for poking

Disadvantages. Don't have much of them. They can use 2 weapons so it means that you will have to buy it and spend money on it. As all crawling creatures find some difficulties when fighting archers and also taos. Until they get good quality armor they are hard to lvl.

I think trojans is the most favorite class of game makers. They are made just too strong. Equal level and equally equipped warrior has no chance to win against trojan. I think they are made to be the best.

Warriors

Advantages: With help of shield they have highest defense of all also shield helps greatly against archers and gives you some more magic defense. Skill superman makes them super easy to lvl. As warriors is least popular class (for a reason) their equipments is usually cheap. They have skill called flying moon. Its not much but with earrings equipped it can kill lower annoying archer in the air.

Disadvantages : Few hundreds of defense that shield gives is not equivalent to few thousand of attack that trojan gets form second weapon. Although shield gives some attack starting at lvl 70 is symbolic. For better lvling warriors can use 2 handed weapon. Then  he must take off his shield. To kill such warrior is as easy as to take a candy from a baby. Even so called 'non-combat' water taos can easily kill them then. Socketed shields are very rare and very expensive so its hard to get more gems. Really find it difficult to fight distance fighters archers and taos. Their armor has the lowest natural magic defense. Playing a warrior sometimes make you regret you are not a trojan 

Warriors are made really poor here. TQ don't know what thy are creating themselves as its warriors when had to have best armors. That's why there aren't much of warriors. But they are good to lvl so can rb easy.

Fire taoists

Advantages: Area attack spells make them good enough for hunting and plvling. Tornado is the most powerful spell that hits hard as is nice to the eye  . They can easily fight anyone if they move fast enough not to get hit by trojans. High magic defense help them against other taos or magic attacking monsters. Healing helps not only when lvling but when fighting archers too.

Disadvantages: Their defense is so poor that a tro of your lvl could kill you in a half of hit. Advanced spells cost much and is hard to lvl. Taos are hard to lvl themselves too. Backsword is also a 2 handed weapon so less gems for you.. + ing backsword or bracelets gives a very poor bonus.

Fire taos are excellent attackers. It mean when you attack someone you will most likely win or your oponent will run away (unless he is much stronger) but if someone attack you (especially tro) you will die in a blink of an eye. Spell will be much easier to lvl if you only lvl spells you need.

Water taos

Advantages: the most popular class for reborns as they can do it at lvl 110 and they get much exp when plvling. Everyone gets double exp when there is someone low lvl in team. Water taos get double exp allways in team and its doubled again with low lvl team mates, so he lvls 4x faster. His skill stigma and revive is very welcome everywhere. Skill divine hare is your best friend when you need to run long distances o you forgot scroll. Ranged attack makes them good enough for fighting. Advance cure really helps a lot as you can heal much  when fighting archers. For high magic defense you are not so aware of fire taos that frightens all other classes.

Disadvantages: same as fire taos, just its even harder to lvl yourself. And skills that are welcome by other players don't give much use for you.

Summary:

Archers: poor attack poor defense, poor hp. But why you should care if they wont catch you. And even if they are weak they are excellent in killing much weaker monsters

Trojans: High attack, high defense, high hp.  Some ranged attack capabilities. What else you could want.

Warriors: High defense average attack average hp. The only good thing you can do is lvling and with superman its no better thing

Fire taos. Average but magic attack, pathetic defense, average hp. Maybe knowing that most of people who use earrings does it because they are afraid of you. Just don��t leave yourself afk because even guards wont save you

Water taos: low but magic attack, average hp, pathetic defense. Reviving peoples is nice but when then people become less aware of dying, die a lot and then starts begging revive revive. And then you dream at nights revive, revive. Don't worry if playing smart you will get reborn soon.

Melee water taos. I think (never tried it) its so popular because its good for booting;
