I feel that Ice Armor is the red-headed stepchild of +DEF. I also feel it's underappreciated and suspect I'll be taking a crack at seeing what I can do to maximize it, as a personal goal. I do take the fighting pool and will get addition IO set bonuses and perhaps -tohit and anything else I can to beef up the mitigation.
The PBAoE dmg toggle, +END bar max refill, +Max HP/Heal, -Rechg/-DMG of Chilling Embrace (still damage mitigation)... IDK, I think there's a lot there that I'd like to give a chance to shine.
I have many meta picks, I'm enjoying picking less played picks lately.
