if you are putting points into dex which exceeds your dex for wearing items, you may as well go for max block, theres no point stopping at 50% block, its just a waste in my opinion.
my sorc has wiz and whitstans, with occy and lidless on switch, and uses the 2 different sets of items according to particular situations... eg. wiz and whitstans for those archers in act 5, and when i dont need the blocking, i go occy and lidless, adds more damage to my spells and gives me max fcr so i can teleport faster.
you wont be needing the fcr, but occy and lidless add more skills, hence more damage.
