Actually that is a good point. Lets see at 100 parry 100 Bushido
Block chance with 2 Handed Weapon 29%, 1 Handed 25%
So that makes for 61% Block chance with a 2 Handed Weapon and 59% With a 1 Handed weapon
If you were to go 70/70/68/69/69 on an elf, you could hit 55% DCI Giving you basically the Block chance 1 handed of 100 parry.
You lose Evasion and counterstrike, but its just a first look into the idea.
