It was 17 parry = +1% parry rate at L50, not 100. It believe though it was 86 DEX/STR was +1% mitigation, which is gone now in HW. This means some Dreadwyrm pieces added nearly 3% parry rate per piece... it was just entirely unneeded.
The Hive Shield has 200 more block value than the law shield, its a different shield type. The law shield should activate more often, for a lesser amount but due to Bulwark and Sheltron the lower activating, stronger, Hive shield is the better choice. And it doesn't eat as many parry procs. It has almost NOTHING to do with the ilvl difference.
