Should not this set be buffed? Tel Var sets are very expensive to farm for weapons and jewels, and block-proc sets are never a bad candidate for Sword & Board bar only.
Perhaps change "current Health" to "max Health", ala Knightslayer, or perhaps remove "direct damage", or double the percentage.
Current 5 piece bonus: When you block a direct damage attack, you deal damage to your attacker equal to 4% of your current Health.
