Get the pillars of might, they are too good to pass up, if you need the extra defense then enchant 20 defense to shield, that should give you enough to get to 536 defense and with the 15 resil from the shoulder enchant 536 defense is all you need to be uncrittable. You'll get slightly more defense when you upgrade your gloves too, another option is dropping the 4 set until you get 277 gear and getting the cataclysmic chest guard and gauntlets of the kraken from frost emblems, they are both upgrades to the 264 T10 but you lose the 4 set. If the 4 set isn't a big deal, then problem solved.
