I'm curious about Echo of Light. I always thought that casting any healing spell after another would get rid of the echo of light, potentially causing an issue. For example, if I cast Greater Heal and then a heal before echo of light is over, then the Heal HoT overwrites the GH HoT.
I'm noticing, however, that everytime I cast a heal on myself, the Echo of Light HoT grows in strength, even if its the same heal. My only procs are SPI procs, and I don't think we have a spirit>SP/Int coefficient, right?
I'm assuming then that Echo of Light hots roll into each other?
