I am coming to a resto shammy with a warrior background. I know melee and tanking but casting and healing are very new to me. I find I am loving my shammy and love to heal. I think knowledge from the instances I tanked have helped me in healing them. I am still learning a lot and looking for advice from all you experienced resto shammies out there. Healbot is great. Healing with lag is not great. I am seriously considering making my shammy my main toon and am open to any helpful advice out there.
