Icy Veins says stack haste to 30%, Ask Mr Robot says go Vers.
Prot warriors benefit from haste as it increases shield block uptime and is great with the T19 set bonus. But Nighthold is a lot of magic damage and if you're in the heat of the moment and miss a crucial defensive even in an inocculous portion of a progression fight it could mean a death. Some bosses barely melee to begin with.
Could Vers be better than Haste for Prot Warrior in Nighthold?
