Ive just finished making my first roll [ a rogue] and now I have begun to make a shaman but I would like some advice on how to play and equip my new character. My focus will to be a healer shaman though I will also make a dual talent for an offensive shaman.

What should be my focus in my armor [ spirit, intelligence, spell power?]

What sort of weapon should I use [ Staff, etc?]

What talent tree(s) would be best for a healer?

What would be best for offensive?

Does spell power effect healing spells?

and also would there be any other useful tips I might need to know?
