After 2 days of gameplay i can say it works great for me.
I want to state the final numbers here:
I gained around 1k stam (not 1,5k) and lost around 2k health. The sustain is great. I feal it in my gameplay that i take more dmg now and have less health, but i think for more experienced players, it is good manageble. I took also the next step and run dubiuos throne now as drink buff, what means another 2k health less, but with 3 wp dmg glyphs. In duels great so far, in cyro you die a lot easier. Next thing for me is to try heavy armor with that build and compare that.
