I'm currently running at GR 80-81...but it's causes me some trouble.
I've completed lvl 80 in 14 min 46 seconds.
As almost all other crusaders, I'm running as Hammerdin (I think it's called), and use Endless Walk (Compas Rose and the Travelers Pledge) + conviction of elements
But If I look at stats at Nightmare-set (LotU + tWH), it does way more dmg (+100% for each item, as well as 4% dmg reduction) for every ancient item.
If you have all slots equipped with ancients (13 slots), it means 1300% more dmg, and 52% dmg reduction, which is way better that Endless walk, furthermore, you can equip a good Hellfire Amulet, and get an extra Passive, e.g Blunt for more dmg on Blessed Hammer
wouldn't this be a better option, or am I complety wrong ? :-)
PS I'm not a Hardcore fan, I just play 3-4 hours pr week :-)
