Malarr's not too far off the mark.
Upgrades in order of priority - I'm going to list conq gear as I'm not sure how many triumph badges are available.
1. Platinum Mesh Cloak from Valor Badges
2. T8 helm - it'll give him the 2 set bonus
3. Indestructable Plate Girdle (crafted item) its a bit spendy so if you can't afford it, get a Shieldwarder Girdle with conq badges.
4. Gauntlets of the Royal Watch (conq badges)
5. Spiked Deathdealers crafted - least vital of the upgrades
Cloak - Defense
Chest - Defense
Wrists - 40 stamina
Weapon - Blood draining
All gems should be solid majestic zircons with the exception of his sword in which I'd put a guardian dreadstone.
Spec should either be 15/3/53 or 5/15/51
These changes will bump him up to (unbuffed):
I'll hit the OT when I have a bit more time
