They're essentially the same as Bright Kingdom. You can tell by the skills. I'd say their descriptions are about right.

I'd go wizard on my mage,
Knight on my fighter,
and Guardian on my cleric.

I'm sure it isn't necessarily, pvp vs pve, but for instance... warlocks and wizards. Warlocks are more for 1v1 battle, while Wizards get to continue the aoe series I believe.
