Trying to evaluate the new shaman changes a bit, it looks like the "Echo of the Elements" checkbox does nothing?
Alas yes, I was going to find out exactly what the proc chance of it is from the various spells but never got around to it. My understanding is that not all spells have the same chance to proc it. If you got some more info on those chances I can try to incorporate it. But until we know those proc chances, I can't add it in the computations.
Hm I should add the 20% buff in, though I have a similar problem with incorporating the effect of earthliving on the various spells.
In general you might be able to measure the effect of the increase on Chain Heal, but frankly Healing Rain's numbers were awesome to begin with, getting it to not be wasted or overheal is harder. Maybe I should add some more knobs to it?
