Looks like my destroyer build also but I took deep gash and madness. my build is same one I was using before IWD. I may make some changes after seeing your build. I also use only r7-8 enchants and a lesser Vorpal because my CW gets all the good stuff because he is my main char. Great build.
My gear score went from 12.4 to 13k on my Sword Master Destroyer. I did not notice anything different other then that. No need for a respec for me :P I was able to take on many mobs at once and not die due to my 3k defense. I just killed everything like usual. Destroyer tree must have got boost due to the rise in my gear…
