Mystic Harvest bugged?

Yes, it's broken. Has been for some time now, since the start of Oct? or thereabouts. :(

For a workaround, drop Mystic Harvest and take Stalking Panther instead. Pick up a high ES chest, plus high Evasion helm, boots, and gloves. Then fit Ghost Dance. You'll end up with so much Evasion that any hit will instantly refill your entire ES.

If you also get some Ev as Deflection on - around 45% on your gloves / helm - and put some points into it on the tree, you'll take way less damage when you get hit.

I'm not sure it's as good as Mystic Harvest, but it is still very tanky. And you can drop the Essentia Sanguis, it's not doing anything anyway.
