Ele sham get everywhere, ranget dmg with totem. But its hard to do dps, when your group/raid sux, cause you lose mana on long fights even if you have every item with + mana regen. (on our pug groups are good eles 2second on dmg meter)
Farming as sham is bullshit, you cant cast when mobs hit you, you dont have proper AoE. Also elites hits you hard if you have shield, you cant solo 50lvl dung like hunter, warlock, mages ...
Healing is too hard, bcos you lose all mana in 5sec if you chainheal max rank those *****s standing in fire.
And when fight is endless, you cant heal bcos there is not much mana regen even with bis items.
