It mostly comes down to accessories. i70 pentameld (Gryphonskin) are currently one of the best options, all around, but the new meldable accessories in patch 2.3 should surpass them in every way. So, I wouldn't worry about it until the patch hits.

In the meantime, you could spec into STR or use some Slaying accessories, if you have them, in place of Fending accessories.
