Honestly those are the classes I would love to see, sad because most of them are in the game... Just not playable.
1)Voriants: with duel axes, or duel swords, or even a sword skins (Viking type fighters) [Gon]
2)Alvens: Archers with a pet capturing system [Jin, Yun,Lyn]
3)Defenders: Sword and a shield [Gon, Yun]
4) Berserkers: A great sword [Gon, Jin]
5)Shamans: Kind of like summoner [Lyn, Gon]
6)Grapplers: Hae Mujin class [Lyn, Gon]
7) Great Monk : A staff or a spear [Lyn, Jin, Yun] or a new race like those wolf people in Lycandi Foothills
those are it for me, but I would love to see, the duel axes with a sword skin, my number one pick!
