Even though it's only a datamined green post (subject to be completely changed/removed), I thought these were impressive enough, to warrant discussion. Personally, I'm really impressed with the enhancement changes, and ESPECIALLY the increase to health when ankhing. I'm dubious if the lava lash reset chance will remain at 15% for each tick of flame shock, though, since we saw it nerfed into the ground already, this xpac.
