Your gear seems alright, I would however change your gems around a bit. You still have a few blue quality gems and some weird gem combination's. DEF + STAM in your head? If you are going for the socket bonus on that, you would most likely get more benefit from a hit stam in the long run for the bit of extra hit rating.
Drop the 8 dodge rating and 8 defense rating gem and replace with a solid stam one. With upgrading your gems to epic. Here is what you could get
Upgrade all gems to epic and replace Shoulders and weapon with solid stams. You would have 87 more stamina which would give you more health. Dont gem for hit on your gear if you are trying to stay alive. If you die because you dont have the health/avoidance, it isnt going to matter if your DPS pulls off you... your dead.
