I was thinking about incorporating this in a build, mainly do to the skill blade cloak which reduces AOE damage by 25%! Only downside is you lose a SnB bar.
I tried this after Morrowind dropped. It is good indeed for tankiness. Only downside is, you are losing the utility of a Destruction Staff, whether it be Ice or Lightning.
If you can survive why not? More dps is always good. Generally if I go that route which I have done s and b dw and s and b bow, Ill just put on heavy damage set ie seventh etc and go max points into stam and keep my dps champ point set up. More extreme content Im not sure, depends on your skill really.
