Of course "ruins" is an exaggeration, Hobbes.
but it DOES make the flow feel bad. and for some people, this "ruins" the experience and the flow of the rotation.
anyway, kalaratic, if they make it refund energy, then that would mean they need to nerf something else, cause that would mean we could get SoD + 3 SS (first one crit).
I think it's better to make SoD just more straightforward, usable outside stealth and doesn't guarantee crit.
this way, it will replace a backstab, not a SS, and you'll be free to only use damage abilities in stealth, and not buffs.
