Elemental Sundering Potential Bug

When I use Elemental Sundering, if the ailment expires before the explosion animation plays, it appears that the skill will fail to do any damage. For example, if an enemy ignited by Radiant Grief leaves my presence before the explosion completes, Elemental Sundering does nothing. My interpretation of the skill was that after the pulse happens, the explosion will 100% occur (assuming there was an appropriate ailment).

I wonder if this is a side effect of patch 0.2.0d: "Elemental Sundering now pauses the Freeze, Shock and Ignites on targets when building up to explode, and now consumes them when exploding. Previously the ailment was removed as soon as the buildup began, this change has been made so targets remain frozen until the explosion."

I'm guessing the fix didn't fully address edge cases like Radiant Grief or Shocked/Ignited Ground. What I'd really like is for Elemental Sundering to remove the explosion buildup delay like they showed in the initial trailers... would honestly feel so much better.

yep yep, also, I noticed that in the video demo of the skill gem, there's no nova buildup happening, the explosion is instant
