Eternal Warrior is useful so you can run Shoulder Charge/Juggernaut and still have lots of armour for FoH. It's only useful if you get shot when using your super. So not very. The Feedback Gloves are not good as alot of people can shotgun you outside of melee range. I like the Peregrine Greaves. Your airborne shoulder charge can one shot a Ram wearing Warlock. Even if they are in Radiance. I've even knocked a few Bladedancers out with it! But mostly I run Armamentarium for Crucible and Crest of Alpha Lupi for Trails. The extra Orb and quicker revives can swing a match!
