PVE Healing w/ Tellicular Current

This build is more based about putting out heals while at the same time regaining mana by participating in DPS(while weak) when there isn't as much damage being put out. While focused insight is a great talent for healing, the shock spell cost itsself costs nearly around 1 cast of a healing spell anyways. Telluric current allows for mana regeneration. At 85 the spell costs around 1.4k to cast, while the damage scales w/ your gear you can still gain b/w 500-600 mana per cast. While the number seems small, it does add up and has really saved my raids and heroics quite often.
