Ghost Shroud does not work when starting es is above 5% of evasion

I spent about 30 minutes watching yeti slam me. When at full es, 1980, his slam is hitting very hard into es and his autos chip the es as well. Sitting still ghost shroud on tooltip says that it will recover 1032 es. When I'm at 0 es from taking off my chest it recovers as normal. And when around that amount of es getting hit heals the character. I can and do get hit way below 1032 when starting from above it. In all cases ghost shroud charges are consumed whether or not the character recovers anything.

If this is a bug please fix it. If not then at least fix the tooltip to say that the skill doesn't work if you have more es than 5% of you evasion.

I think I'm just mistaken about the mechanic. Please delete or ignore. Ghost shroud brings you es to the amount of the shroud right before a hit and then does damage against it. If your current es is higher than the shroud, then it uses the higher value. But this isn't recovery! At least make it do what the skill says it's going to do, and the first hit is totally useless! This skill is very misleading.
