Long time healer main for raids, but switched to RDM for raiding. No specific reason, just a little burned out on healing, I was unsure of the new healer changes and RDM just looked too cool to pass up. Now that I got experience in the expansion, I don't regret my decisions. The healers were a little messy before the QoL buff in 4.05, but in the meantime I've been playing the crap out of RDM. The playstyle is really straight forward and amazingly satisfying to build up mana to go into melee mode, jump out and just nuke someone!
