Hi, for farming, it's great to have a DB or WL with spoil. With them, you'll have elements and beasts. To do bosses, you need to build a PT with DB/Titan, Jud, 2 Sk, and a Necromancer.
For PvP, you can build several setups. Since there aren't many, I recommend a CP Mage/Cancel. They're very good at defending and have an advantage in closed environments.
If you need a cardinal, I'm looking for a clan hehehe
