Thanks guys. i got the Canni AA, and i love it. Endless mana rocks. I can get off a couple pained memories while canni 5 is refreshing, if am in a pinch for mana. Just hit Canni 5, PM, PM and then Quiescence, and poof... full health and full mana. need to get Breath of Trushar, for that 620/tick HoT. Having a hard time parting with the 15K for the spell, and havent been able to get a rune to get it myself.
As for soloing or off tanking stuff at level 70, as long my dog is between me and the mob and I can keep him alive it's all good. For the most part, i try to keep from getting hit.
