The biggest problem I see is your trinkets, you should be using EH trinkets over avoidance, get the Glyph of Indominability from triumph emblems and The Black Heart from reg ToC
Enchant your shield for +18stamina, Titanium Plating isn't good for raiding.
I would re-enchant your cloak to +225 armor over your 23agil flexweave as well.
You could drop your glyph of schockwave for glyph of shield wall.
other than that it seems like you just need to gear up some more.
