I like the idea Kaze and your post is extremely well thought out and organized. The skill tree maybe a bit overused in mmo's but how else would you organize it? I'd be willing to have these classes back to have stradegy and class uniqueness. Of course adding the extra classes will be awsome too like Bard/Dancer or Summoner/Blue Mage.
Now for something else I thought of they would need a starting class based on the skill trees you presented so I was thinking something like this....
Entertainer > adv. job Bard/Dancer = Would participate in a variety of musical or entertainment quest and use musical insturments and daggers or knuckles as their arms.
Tamer(this beginning class is tough to name so suggestions would be nice ;3) > adv. jo Summoner/Blue Mage = Would participate in a variety of monster taming, monster skill knowlege quest and use staffs and swords or daggers.
That's all I have atm!![]()
