Archer help

[Luciano1997]

To make a long story short I have a level 21 archer but I've messed up since the beginning (it was my first Fiesta character). I'll make a new one.

So I want to know:

1. What's the best build for an archer?
2. What production skills can I benefit from most?
3. How should I empower my skills?
4. When I reach level 20, should I choose Bow or Crossbow?

NOTE: If you know of a guide with all this and more, post a link.
