“The base healing spell that healers are supposed to use until they gear up enough to have a significant amount of regen and throughput might not have a role in the game anymore. They are situational after you are no longer in greens and blues.”
This is referring to Heal, Holy Light, Healing Wave, Nourish.
The problem I see with the spells is that they have such a long cast time for little throughput, but their advantage is infinite mana sustainability (love it). Down the road of a expansion and its increased difficulty, healers cannot afford to keep up with damage with longer cast times and low throughput.
Restoration shaman uses their Healing Wave almost as a main ability because of how fast Tidal Waves makes it. Why not give the "base heals" faster cast times? Although I would not mind simi returning to a wrath/bc model with one cheap fast casting heal (Lesser Healing Wave), and a great heal (Healing Wave), along now with all our other heals Cataclysm and Mists of Pandaria have added.
Your thoughts for Heal, Holy Light, Healing Wave, Nourish?
