Also to the OP, I would like to say this.

It looks like you've been gone for a couple years from the game, and have only recently come back due to me looking at your levels and forums posts. I would greatly suggest getting a better grasp on multiple classes skills/spells/abilities before trying to come up with a possible class for the game when you need to do your homework on what would and would not work in game. You're simply asking for too much, and trying to keep it too much like in FFXI.

Wait until you see the changes of 4.0 and get used to them, them possibly revisit this idea you're trying to form. Remember, you don't write a book report just from seeing the cover and the first few pages.
