Random thought: It would be great if EnvM could be more front-loaded like Wild Growth with an instant tick.
Still, does anyone know the SP coefficient for Healing Spheres? I tried messing with them, but the numbers seemed lower than what people are throwing around here. I guess I'll estimate it tonight, if no one knows.
Are you using any macros to cast Healing Spheres? It seems clunky having to click twice to cast a heal on the tank, especially with a 0.5s GCD.
