Good question. Dex help for % block. Also, they help for other cool stuff. If you dont need MF (in that case, I would use WT and maybe Chancy), these 2 items help with :
Boots:
Good frw (40)
Dexterity
Magic Resist
Cannot Be Frozen
Gloves:
Dexterity
Life
+20 to Dexterity (2 Items).
Pride might have a slight advantage but I prefer Insight for qol.
but the point of the pride build was that you dont have to use conc, and that way you'll have a ton of QoL cos you can use redemption as your main aura
you basically get to put those 14 points into vigor synergy, then get lvl 20 conc from mercenary
then you self use redemption for infinite mana/life while using either foh or hammer
you need a decent mana pool though, so soj instead of bk and frostburn as gloves and maybe a few 15-17 mana sc's (you can use 7 mf 15-17 mana ones)
