Ok, i misread necrogenesis text. My bad. So nothing from THM can actually be used.
For CNJ, tho, stoneskin is pretty good due the hight enhancing magic from VIT. I've been trying to combo Sacred Prism and Stoneskin and it working pretty well in heavy damage fights. Also, need to see if the enmity is increased this way since a "curaga" can also draw some cool enmity.
I was thinking...a good adjustment to the class would be path of the storms being radial AoE again and increased damage or increased enmity as WS bonus. But i'd also change the bonus condition from "WS from behind" (which nearly killed any possibility of using Whrilwind in combo against multiple monsters) to "2 or more enemies at AoE range". This way it would only have the bonus effect if used against groups of monsters, restricting the use against bosses and stuff, but making it very effective where it matters...group fight.
EDIT: Forgot to say why i think it's a good change....it would leave MRD with a tank combo (heavy swing one), a DD combo (brutal swing one) and an AoE combo (path one)
