2nd coil has a savage version, which is more along the lines of current ultimates
Uhh, not even close.

2nd coil normal, as we have it now, are nerfed versions of their original encounters; many mechanics are nerfed to be not as fatal as they used to be (for instance, Rafflesia's Blighted Bouquet does way less damage instead of the instakill it used to be for level 50s if you got hit by it). 2nd coil "savage" is meant to be more faithful to the original versions of the encounters.
