I noticed there are new shields at Sergeant Third Class Rank which are purchasable for 5000 seals. They have the highest block rates (increases chances to block) in the game. It would be nice to figure out how block rates scale to each other and the percentage of increase. To see if these new shields are worth it. Has anyone did any parsing of block rates?

Gridanian Buckler
Block Rate 168
Block 71
Evasion 15
Lominsan Lantern Shield
Block Rate 126
Block 86
Attack Power 15
Ul'dahn Hoplon
Block Rate 131
Block 107
Dexterity 2

Shields before the patch which were top tier:

Canopus Shield
Block Rate 94
Block 122
Strength 2
Piety 2
Evasion 4
Vintage Kite Shield
Block Rate 92
Block 120
