Barbarian Shaman/Warrior Duo Question

[Cyph]

Hi all! I play my Barbarian Shaman exclusively when my friend is on with their Barbarian Warrior. Currently we have been hitting BlackBurrow but after turning in our latest fang haul, we're both level 17 (woot!). Personally I want to stick around the general area a bit longer and reach 19 so I can buy those spells (money is still tight) before deciding to venture out further.

So, a couple of questions;
1) where else nearby could we use to level (other than some more fangs from BlackBurrow). Something that would drop fine steel or bronze would be good so we could make some plat
2) in terms of our play style, I find that the moment I DoT a mob I draw insta agro and it is quite difficult for the Warrior to taunt it off. Am I better off just keeping the Warrior buffed and healed, letting him do the work? At our level, are debuff spells such as Disempower or Walking Sleep worth the mana cost?

Any other advice would be greatly appreciated [You must be logged in to view images. Log in or Register.]
