As far as i know, warrior 55's still get laughed at...
only 2 energy regen, base energy of 20.. other classes are more suited to the 55 build
As for the UW, my preference in armor is sentinels with 2 radiant insignias giving 25 energy. But i think the best armor is knights, as it reduces physical damage. You shouldnt be using axe skills or using your axe for that matter, unless you want to build adrenaline, and its a waste considering you will only have your axe equipped 50% of the time
Im assuming you are trying to use Vengeful was khanhei farmer, correct me if i am wrong.
* Armor: Full armour set of Knight Insignia's is best, although not vital.
* Weapons: A +5 energy sword/axe/spear with a +30hp or +7 armor vs. physical dmg mod. A shield with +30hp always and damage -5 (chance: 20%). Also shields with stance bonuses are advisable for the running portion and you could replace the +5 energy weapon for a weapon with "let the memory live again" to reduce the recharge time of Vengeful Was Khanhei.

I also recommend a superior absorption rune and at least 600 health, which shouldn't be hard to attain since you don't need any superior runes (absorption doesn't take health off)
for W/Rt UW runs, I use:
gladiators armor (+energy) 12+1+1 strength, and a +3 strength armor part for signet of stamina
for mindblades I use knight's armor (-3 physical damage) - not that important, you can go with your gladiator set also - and lieutenant's helm (-20%hex duration)
attributes:
12 restoration
12+1+1 strength
rest +1 on tactics
