what are some classes and jobs that you would like to see in 3.0

[Exstal]

I'd like to see;

Dark Knight OR Samurai OR Viking: Tank
Green Mage: Healer

Many of the suggestions in here are awesome ideas so i figured I'd add some of mine:

Class:Archer
Job:Ranger
Role: DPS
Primary Job skills:
(lvl 30)Long Shot: Fires a shot that deals damage to the target up to 30yalms away.(130 Potency),
(lvl 35)Running Shot: Deals damage to the target and increases user's movement speed for 5 seconds.(50 Potency),
(lvl 40)Sniper Sight: Increases ranged accuracy and damage.(no damage),
(lvl 45)Flaming Arrow: Fires a shot that deals damage and fire damage over time for 30 seconds.(130 Initial shot potency and 30 DOT potency),
(lvl 50)Dynamite Arrow: Fires a shot that deals damage to the target and others around the target.(150 Potency)

This class would be imbalanced, hope you know. Since Bard is balanced around having songs, having the same class with straight DPS skills makes it stronger than all other classes.
