Warriors
Overlords-Very basic. Not strong and not weak. Very average damage if you were to give a punching bag all you can do for 5 seconds. Health hungry for fast runs with bloody roar decent clear speed.
Dragoons-Mana hungry. Not strong and not weak. very average damage if you were to smack a punching bag for 5 seconds. Takes only 5-7 skills to pve efficiently
Mages:
Invokers:- Easy to play.Very high damage. X spam all day for dungeons. For Mission maps you may need to use 1-4 skills to rack up points for an SSS.
Sorcerors:- Easy to play. Not strong and not weak. Damage output is slightly above average if you were to hit something for 5 seconds. Excels at mission maps. Few skills required to clear maps/mobs.
Thief:
Ninjas:-Mana hungry. Quick burst damage. Should be easy to pve with. Decent damage since they moved critical damage from 300% to 600%.
Savage:-Fun to pve with just 2 skills(headspin/windmill) given enough movement speed and damage. Decent damage in pve.
Archer:
Destroyers: Easy to play. Low skill variety. Very high burst damage with snipe, especially now that they can get up to 500% CD.
Sentinal: Easy to play in pve. good clear speed given enough damage. very high damage with awakening skills.
DragonKin:
Twins: made for pvp, you can still pve if you'd like. Mana hungry, above average damage(Given that you know how to attack for high dps).
Summoners: Easy to play. Strongest dungeon clearing class and a strong pvp class. Can easily solo the end game boss with 1 button. x spam oriented. May require you to cast skills to get an SSS in mission maps.(This is probably the all around class if you ever want to pvp or pve at top tier)
I tried to refrain myself from saying other things since you may already know them so I gave the basics.
