Blader- Bladers are the fastest (atk speed) melee characters. They use a combination of light yet maneuverable armor (Martialsuit) and 2 one hand swords (Blades or Katanas). Having light armor they have less "def" but way more of a dodge rate. They make great PvE and moderate PvP depending on how you train them. This makes them a wise class to pick if you really like PvE or duel wielding.

Wizard- Wizards are the basic magic class. They use what are called "orbs" which are used as magic amplifiers, and light armor (Martialsuit). Orbs attach to the the character's wrists, and the orb on the right wrist summons a staff (mostly to make them look like they use a weapon/ also the cool factor) later on in the game they have incredible (both look and power) magic attacks/skills some of which have huge AoE (area of effect). In PvP they can some times win untouched depending on a number of factors. Based on who uses them and how they train, wizards can destroy or just plain get they @$$'s kicked. usually good for both PvP and PvE.

The next 3 classes are classified as "Force" classes. Force classes are more like hybrids. and they are...

Force Archer- Force archers are in ways much like wizards. They use "Crystals" in the same way wizards use "Orbs". Crystals tend to give less magic power but more accuracy. They use a well balanced armor (Battlesuit) giving similar Def and dodge rate. Force archer use magic to summon a "astral bow" out of their crystals. Astral bows not only look very cool but also help amplify there ability's. Also they act as the healer/cleric class making them a fully capable combat enabled medic. (personally my favorite class)

Force Blader- Force bladers are a magic/sword hybrid. They also use the well balanced armor (Battlesuit). They use a "orb" (commonly use crystals) on there left wrist while wielding a 1 hand sword (blade or katana) in there right hand. This gives them the advantage of ranged magic attacks to use til the enemy gets close and they beat em' up with the sword. They have the ability to enchant there sword with "fire", "magic", and "lighting" among other things. This makes the a really well balanced class.
