DFO Basics?

Base your decision on which job to take at level 18 from which skills you liked.

I disagree. The couple skills per subclass you get before 18 aren't really enough to make a decision. Read up on the style of each subclass before making your decision, or just do what I did and pick one randomly.

If you don't want to buy NX, you can sell purple, green, and pink items on dfosource.com (and here on SP in the trading thread, if anyone ever reads it...)
