what stats do i need? what cross job skills should i use?

Allocate stat points to STR and INT.

Gear for STR and ATK. Do not worry about gearing INT until max level.

Always select the weapon with the highest damage rating for your level--at or below, don't try to rock Lv.50 dated weapons at level 20.

In a party of 4 or more, you will gain enough accuracy from the PT bonus to max out hit rate. You may wish to keep a set of ACC+ rings/helm/etc. for solo and lowman play, however.

And don't forget to smile.
