The only two things that immediately come to mind are your belt and legs. I'm just wondering why you're using the [item]Rubium War-Girdle[/item]. If you want a better belt for both effective health and threat, I suggest getting [item]Sha'tari Vindicator's Waistguard[/item] from the Arcatraz key line. If you already have it, ignore this.
The other thing I noticed is your pants. [item]Timewarden's Leggings[/item] is better once gemmed and armour-kitted in terms of effective health. The only thing you lose is about 1(?) block value from the strength and some defence that you could make up from the belt. I understand that gemming and enchanting the Timewarden's could be expensive though (I have a mixture of +9 and +12 stam gems because I can't afford all +12 =P), but it's something to think about. Apart from those two things however, you have a very nice set of gear.
