The archer seems to be pointless.

Warrior is kind of the pointless one when the game first released. They cannot do much damage and cannot tank well. And I remembered most party I was in before were Enchantresses and archers. They just recently fix the warrior to make them stronger and more durable.
Archers are mainly damage oriented if you have it well equipped and speced correctly.
Enchantress are a bit weaker than the archers damage-wise and relies on MP a a lot, but are more of a supporting character with heals/buffs. That doesn't mean they cannot nuke the hell out of the mobs, but you just have to be more careful playing them. Even a little Cure magic can attract mobs from far away. I've seen many enchantresses died that way.
I felt getting an archer well equipped is easier than getting an enchantress well equipped. You have to have some rare and nice armor/weapons with +MP/s to be able to use your MP profusely. If not, you will find yourself drinking a lot of MP potions.

If you have been in an all archer party, you'll find they kill as they run through the dungeons without stopping.
The main thing for archer is you need a high DPS weapon. Get a nice heavy crossbow and you'll be set.
Also, archers get wealthy easily and quickly because they don't get hit much and thus gathered a lot of money at higher level...
