ED is such a darned if you do darned if you don't skill in the SCH's toolkit. I agree with the general consensus that we should be healing with our Aetherflow over dumping it all into ED but we still need a skill like it for the sake of not wasting all of our stacks. I wouldn't mind more to do but at the same time this particular element of the sch toolkit is just going to always be problematic in a game like this.
