Obviously I don't know your build, but I recommend taking 10 points in defensive for the 200+ toughness when knocked down and w/e. I also recommend you switching out one of your 3 slot skills and make room for Banner of Defense, and use Battle Standard as your elite, you might already have done this, but it helps me a lot with survivability as a generally offensive GS/Axe+Shield build!
This is of course only for dungeons.
