I agree with Merth. I run a samurai paladin, and with the lightning strike ability, Enemy of One, Consecrate, and Honor abilities, I have no trouble with most mobs. I dropped focus long ago, seeing as how the Paladin spell Divine Fury fully restores stamina in one cast. I personally would lose the Arms Lore and Meditation. With a good mana leech weapon, you will leech back enough mana to keep using your abilities, and save yourself 90 points. Good luck!
